BHP UK Reviews 54

I purchased BHP UK's ECU Flasher and tuning service for my 2020 Kawasaki H2 SX SE. After a month of dealing with them, I can honestly say this was £648 wasted.

Before everything, I must say that the manager didn't offer to fix the map AFR as I wanted, and also to give money back bcs he is not able to tune below 3000. Now the full story.

Problems started immediately - we agreed on a £50 customs invoice, they never sent it, and I ended up paying £149 (30% more). I sent them my exact setup: IXIL slip-on, K&N filter, Dominator decat, no exhaust valve. The main reason I bought this service was to fix the jerking at 2000-3000 RPM during city riding. This is a well-known H2 SX issue. When I tested their map, the jerking was still there. Their response? "We do not tune below 3000 RPM." They literally admitted they cannot fix the problem I paid them to solve.
I asked for a revision. The second map was worse - rough idle, jerky throttle, terrible quick shifter. They told me to use the first map, basically admitting failure. I spent €50 on professional dyno testing which showed AFR of 12.8 - leaner than the safe 12.3-12.5 range for a supercharged engine. They also didn't configure the map for my setup despite me providing all details upfront.
When I asked basic questions about what they modified (standard practice for any tuner), everything was vague "trade secrets." When I showed dyno evidence, the manager became defensive and accused me of trying to steal their map. Absurd. I'm just an owner trying to verify the map won't damage my €20,000 motorcycle.
I requested a refund per their published policy and offered to return the device. Response: "I will not entertain any refund request from you." They refuse to honor their own guarantee despite clear evidence of defective work.
Bottom line: £648 for a tune that doesn't fix the stated problem, has questionable safety, wasn't configured correctly, and comes with hostile service. The only positive was +15 HP. Save yourself the money and frustration.

EDIT: I got money back via Charback from Mastercard. So big WIN for me and proof that I was right.

For Cal - You were not able to tune bellow 3000 what I asked and fix AFR, end of story mate. Good luck with tuning!!

I can't fault the product or the service. My Multistrada V4 Pikes Peak is transformed after uploading the map. The bike comes alive at 6k rpm and doesn't stop.
The guys at BHP talked me through the process (uploaded via the flasher) and everything was straight forward.
The best single investment I have made in this bike.
Thank you very much.

First class service from BHP, staff are really knowledgable and helpful when phoning or emailing with queries.
Very quick dispatch of flasher tool, before 1030am next day, and a quick turnaround, only two days, to get the written map back. The process is simple to retrieve ecu data in first instance as is the read/write process when you get the map back. Bike seems smooth and more responsive. Thanks BHP

R13000GS remapped using their handheld unit. Improved fuelling, response and power anywhere in the rev range and no hint of any flat spots in the delivery. This is my second remap by BHP UK and I will not hesitate to use them in the future. Highly recommended 👍

They are amazing , found that my bike had been previously remapped. Checked the map which was ok and told me all the information.
Amazing as they could have remapped and I would not have known and charged me . They discover not totally professional outfit , I would not hesitate to recommend them and I will be taking all my future bikes to them

Booked my ducati desert x in bhp uk for a tune up 21st August. Before a wales off road trip. was told he has done 17 desert x before so i thoughti was in safe hands .Traveled 216 miles to get to Burnley to get there 9.15 am. cal tuned the bike on the dyno machine took a good few hours doing this I found he tuned and adjusted it for top end power I didn't want this as I was using it for off road use like I said and with nobby tires nobody would want top end riding so I took it to Wales later that day bike was great at motorway speeds but at below 5000 rpm it ran terribly and unrideable ratting like it was in wrong gear in any of 6 settings fantastic over 70 mph so contacted bhp to take it back ASAP after many emails and phone calls they finally got back week and half later to me giving me a date to go back 17th September fine so another 216 miles each way I decided to stay in a hotel in Burnley day before and took it in back of my friends van as the weather was very windy and rainy took the bike out of the van and bike was rolled straight in I has to remove the mirrors and screen had small problem after it was rolled up on the dyno the front brake was locking on only found out this when the bike dashboard was flashing red as it was blasting round to 10000 rpm on a cold start and wasn't warmed up to temperature not happy about that I adjusted the brake leaver and tighten up mirrors bolt etc I told cal my problem that it wasn't riding well under 5000 rpm he said my chain was loose and that was the problem so he tighten the chain still on the rolling road it was tightened far to tight in my book but took his word for it( it's should be 47 mm and on its side stand weight) and not tied down on rolling road cal has the tools but definitely no mechanic he then spent the next few hours on the rolling road adjusting on his computers I test rode it after and it was much better now at lower speeds 3000rpm onwards so i was Happy again I loaded the van again cal come over said am I happy as he said he didn't do anything only it just needed the chain adjusting why was he so many hours on the rolling road if it only needed a tighten chain what was a total lie this guy has loads of great reviews ???this is why I travelled so far to use him to get my bike spot on after my decat my summary is if you Decat your ducati your not going to stop the popping and back fires so so keep it as it is 500 pounds on the very small amount of benefits you get from this tune is not worth the potential damage I did ask for a dyno tuning print out of before and after the tune after 2 phone calls and many emails I got graph emailed to me 24th September just to add this bike has a brand new chain and sprockets fitted by a local motorcycle shop fully serviced with new air filter funnel web new o2 sensor oil and filters all before my visit I didn't want my money back I wanted my bike back to how it was rideable at traffic speed and for off road use its back to how it was now

Since i live in Sweden with limited tuners for my Rocket 3 i turned to BHP UK. Fast delivery of the flasher, and once the file was uploaded to them it took a few hours to get it back. The map was spot on, this is how the bike should have been from the factory. Night and day difference in how smooth it runs now, and how the power delivery is. Bike is std in regards to exhaust and filter. Highly recommended.

Got the remap for my Harley sportster s due to mods made by myself which left it not as sweet as it should be .
After the remap it’s a different bike .
Many thanks to BHP U.K.

These guys are magicians. From start to finish these guys were so helpful. Emailed me back straight away when I had a query. I decided to flash the bike at home as the ride over to them would be 3 hours
Flasher got delivered very quick and had full instructions on how to download your current data on to it.
Few days later I received the modified data file and installed it that night.
Next day took the bike out to see what it was like, hoping I didn’t get the placebo effect……. And boy was I wrong.
The bike felt different, more responsive.mo jerking at slow speeds and revs and Jesus Christ……. You wind back that throttle and she pulls like a rocket ship.
If you want a superb remap with amazing customer service then BHP Uk are the guys to make that magic happen.

Top result, different bike to the bike that went it👍👌🏻😎

Fantastic communication hand held device very easy to use my first map wasn’t quite right I emailed they were on it straight away sent another map perfect very happy

Cannot speak highly enough of Qal and the BHP UK Team.

Many tuners shy away from the Ducati 1098 as its lumpy engine nature can be very challenging to correct.…

I tried having it done locally but despite their best efforts the lumpy engine nature remained.

Qal and the BHP Team were only two happy to accept the challenge and have completely transformed the bike.

This bike is now a pleasure to ride around town at real world speeds. The smooth consistent power delivery at all RPM is a privilege very few with this engine get to experience.

This is the way Ducati should have mapped that engine 👏😊👍

What a pleasure it has been to deal with Qal, David, Joe and team. All thoroughly decent people. The service, and product has/is fantastic. Fitted end can, and re-map to my Streetfighter V4 SP, what a difference, particularly in the noise front!! Highly recommended.

I bought the BHP UK flasher from “A Bike Thing” after watching their YouTube video review of it for the GS1300. I hadn’t expected the change in the bike that the re-map gave. My GS1300 is stock, and the re-map has transformed it. The bike is noticeably faster. But that isn't the most noticeable thing. It is now silky smooth on acceleration right across the rev range in all gears. It is nothing short of spectacular. Plus great service and advice from the team. Do yourself a favour, get one!

2025 BMW M1000XR Black Widow de-cat, DNA filter and BHP UK ECU tune with their “flasher”.

What excellent service - immediate responses to emails and phone calls

I mistakenly had a BMW service after reading the OEM ECU file and sending it to be modified resulting in my new file not being compatible when it came to upload. Within an hour BHP UK had received my new file, modified it and sent it back to me. Awesome customer service and no charge for my error.

BTW, if you want to transform the way your bike runs and get the best possible behaviour from your engine - don’t hesitate and invest in a BHP UK tune. Well worth the investment. Amazing.

Had my Ducati 1260 Diavel remapped by BHP UK this week. It's made a tremendous difference. More power, no dips or flats spots and more urge everywhere, but particularly in the midrange without having to dig deep into the throttle. Feels far more responsive, like the bike Ducati would have wanted it to be if the Eurocrats had let them.
It's also much smoother and pulls higher gears from lower in the rev range without lugging. It's just a far niver bike to ride now. Clearly knows exactly what he's doing and has taken pains to trim fueling and throttle very precisely to give optimum rideability. I would highly recommend BHP UK at Burnley. I have two other bikes I will be taking to them in due course.

I booked in to BHP uk last month, the total experience was brilliant from start to finish, he transformed my Ducati Streetfighter v4, he managed to smooth the power delivery and increased the mid range power, if I need any motorbike remapping in future I would have no hesitation in taking it to BHP. Thanks again for a brilliant service.

Very nice people to do business with.
Having watched numerous You Tube Vids I decided to get my SDR 1290 Flashed at BHP UK.
The standard KTM package seems well sorted actually and in all honesty since it`s been done by BHP, I can`t really feel a power increase.
That was not the reason for me taking it there though.
I was hoping for my Duke to run a little cooler and hopefully smoother at low speeds (I live in Wales ).
After the flash it was far better in 2nd at 20mph and indeed 3rd gear at 30mph, so I got exactly what I asked for.
That's only part of the story.....What I didn`t expect was just how smooth it was around 5k revs.
I`ve find myself riding it like a 4cylinder now (Keeping it at higher revs in lower gears) definitely less vibes !
Mid range pull is way way smoother and so is cruising at 70mph in 5th.
I haven't noticed if it runs cooler but I now have the peace of mind knowing it`s NOT running lean anymore !!!!!!
Thank you BHP.
Its worth the money.

To My KTM 1290 Superduke Gen 3, Cal and the Team did an amazing job on Remapping ECU spent time getting things just as they wanted, absolutely spot on fuelling, pickup and throttle response have improved massively it has made a massive difference in riding so much crisper i would defiantly recommended there services they went over and beyond to make you fell welcome

AWESOME!! I'm in the USA. Took a leap of faith after watching their youtube video. Unbelievably satisfied with the result of the remapping of my cb1000 Hornet. THANK YOU BHPUK!!
