Tunit Reviews 

Dealt with Tom Scott at tunit, excellent service, replied instantly to all my whatsapp messages and helped me find someone to fit the product
110% recommend

Had a peddle box and advantage 2 installed myself on my c250 cdi, wow what a difference it’s how Mercedes should have made the car from stock.

I found the staff extremely helpful talked me through fitting the unit. I've noticed a difference in power & torque. And also fuel economy. Would recommend Tunit 100 per cent

Professional helpful team of technicians,
Tom S sorted my 2020 np300 Nissan Navara out, fantastic products amazing after service.
It's improved mpg, throttle response and overall driving experience.
Thanks Guys

Good morning I’ve just had a Tunit power performance box fixed to my Ford ranger and it amazing I’m lost for words changed it in to a animal now 😃😃 loads my power and better on fuel ⛽️ Neil Wheeler

I’ve dealt with this company now on many occasion's and they are nothing short of professional and simply the best in any form of tuning and knowledge associated with this. Michael and his team are on point every time with their prices and I’ve replaced my units time and time again as I replace my vehicle's. Their knowledge stretches from cars right through to trucks and any form of transport. He has even made a huge difference on my finances for all the company vehicles I work for . Get his team involved as I promise you won’t regret it and end up saving a fortune

I bought an advantage 3, took ten minutes to fit it myself with no tools required and have seen an increase in power and MPG. Great bunch of guys to deal with. No hesitation in buying from them again.

Having used Tunit modules for over a decade, when we changed to a Citroen DS5 self charging diesel hybrid, I bought one for this.
Citroen electronics can be pernickety at best, and sadly the unit set off multiple warnings across the CPU, and the car wouldn’t run. I managed to cancel the codes and get her running, but each time I tried the Tunit module, the same thing happened.
I spoke to Will and the Team in Chorley. I happened to be passing by from north of Inverness that week, so they agreed to check everything over (was looking to go south by bike but the car needed sorted).
What a great, friendly bunch. 4 hours of work revealed a fault in the unit - first time in a decade of experience. The unit was repaired, reconnected, all the codes cancelled, and the car has ran like a dream since, and no charge since it was a module fault!
I am still learning how to get the best from the hybrid as winter changed the characteristics….. but, there is a 5-10% improvement in economy depending on temperature and R foot!
Great service from a brilliant team…. thanks guys. Sorry about being so slow to get the review in!

Arrived very quickly, well packed
& customer services are very very quick at getting back to you..
Need few more days to test optimium plus, as Iv only plug it in today...
I have tested sports plus I did feel a difference as I have automatic

Had device retuned to fit my Q7, from Mercedes Sprinter.
Found Tunit made throttle control smoother and better performance overall. MPG still needs working out, as I haven’t been on a long run.

I've had three Tunit sets for three different vehicles which we still have. Wil has been exemplary with his help and support with recommendation and after sales car on which device to use on the three VW's. I know my Mrs who likes to use the accelerator is pleased with the performance and smoothnes. I can't say if she has noticed better range but on my 1.6 I get better performance and at least 80 miles extra per tank, I was getting 740 per tank now its regularily way above 850.

Defo recommend if you want more push in your car

This is the second time I have fitted a Tunit to a vehicle and once again was pleased with the results.
I was a little disappointed to say the least with my new T6.1 Transporter (2 ltr 200hp) only returning 30mpg at best when driven steadily. A lot of the Journeys were only commutes or 100 mile trips.
Following the installation of the new unit, which was a great experience. the mpg increased to 33 with the unit set at mid point -5.
I took a 250 mile trip up to the North West from Norfolk and this raised to 36 mpg.
Before the return trip I raised the setting to max and was getting just short of 40 mpg for the journey.
Back home and the normal routine I'm returning a 35/36 mpg, greatly improved figure and noticing no detrimental effects on how the vehicle drives.
Thank You Tunit.

Very happy with my purchase. I bought a reconditioned unit at a great price. I am getting an extra 10mpg now its fitted.

Tunit power pedal is a very good product I have had two in different cars and found them to be very good 👍

I got a Tunit fitted to my Jaguar XF 2.2D Sport as it was a bit flat on acceleration particularly from a standing start at roundabouts etc.
What a difference! I really did not expect it to make so much of a difference in both the performance and the feel of the car. Before my Jag felt like driving a taxi, now it performs like a powerful sports saloon.
The fuel savings I was particularly surprised by. I used to get about 37-42 mpg on my usual trips (about 30-45 minutes each through 90% urban traffic or slowish country roads). Now I'm getting 47-54 mpg every time. I really am impressed. I was considering selling the car as I really hadn't grown any emotional attachment to it before because it was a bit lack lustre, but now I'm falling in love with it for the first time! Well done Tunit and your mechanic.

The guys at " Tunit " could not be more4 helpful . Got my mate Dave Bardwell to do the instillation as he is a mechanic and I am not . He got on the phone and the the " Tunit" staff sent through pictures and detailed description . Got the advantage 3 and Power pedal pro fitted . Strait away there is a very noticeable sharpening of throttle response and generally more grunt . Only driven it for about 8 miles so far so cant comment on the fuel economy just yet . Well pleased . Can highly recommend " Tunit " Andy Stubbs .

I've only had my optimum for a week now but to be honest I can't feel any difference to performance or fuel economy. Maybe I have to drive more for it to adjust to my vehicle. I have been in touch with Tunit and they have A1 5 star customer service. They reply quick and respond very well to the emails. Overall seem like a decent company. Fiat grande punto 1.4 16v NA.
Further to my last comments. I've drove about another 150 miles and I can notice an improvement midrange especially can feel more torque now. Good product.

Fitted the tunit box to my lads discovery 300tdi ( 235000 miles auto with straight through pipe, large intercooler and free flow filter) and after adjusting it, took it for a spin. What a big difference it made. Well impressed. You do get a puff of black smoke when accelerating but obviously that's the extra fuel being injected. Seems to have upped the torque quite a bit as well as it now powers up hills easily. Well recommended

Advice and help offered by Will was spot on, as was the fitting by Paxtons which was done in no time at all.

Once I left the yard I immediately noticed the improved performance in both power and efficiency and a couple of thousand miles later I’m definitely enjoying the increased fuel economy!
