I’ve Known Chris for a lot of years very nice down to earth guy, I found will help you as much as he can and make time for you.

He’s mapped a few of my cars now and has always been very clear in the process and what i need to do prior to me brining him my car.

Most recently I acquired an F32 420i as a daily driver while I loved the car it was lacking the power for a good safe over take.

Knowing the B48 engine is very capable Chris was the man for the job. I had the map done by him then independently dynoed to see what the results were as usual fantastic not that i was fussed really the car drove incredible on the road the dyno was just for more knowing what it was doing.

100% the best tuner I've ever been too. Was well worth the 2.5 hour drive out to get my Insignia running how it should of been! Spent hours fine tuning the tiniest details. Knows everything there is about cars and tuning. This guy is relentless! Can't thank you enough Chris! Will see you in the new year.

Chris did an absolute number on my car. He transformed it into a little pocket rocket. Super easy services and very kind too. He took a last minute booking also very good with communication. Could not have too my car to a better place!! Thankyou again will definitely come back in the future!

Had my Map revisited last week with Chris at Dervtech due to fitting a new turbo. First map was at the unit in Stockport on the dyno and I was very happy with what figures I came out with and the car was amazing. This time no dyno and met at a mutually convenient place. A completely different tuning experience, I would say a better tuning experience! I felt completely part of the process with Chris talking me through all the way, first we went on a run to do a bit of logging (me driving and Chris plugged into the car) went back for Chris to play with the map, a couple more runs out and every little blip ironed out I now have a car that is truly amazing to drive and blisteringly quick! Ok I haven’t got a dyno print out for my figures this time but in all honesty I don’t care because I know the car feels a lot faster and when curiosity gets the better of me I’ll pop along to my local dyno and see what it’s doing not that it will matter.

After experiencing both dyno tuning and road tuning I think I’d definitely go with road tuning again because the way the car drives now is spectacular!

5/5 Chris was absolutely brilliant. I sent my f56 mini cooper s for a stage one tune and he actually managed to deliver results even better than expected. He was very professional, knowledgeable and all around a great chap who has a great understanding of his field of tuning. I would really recommend his service and he created a great map with just on the road testing and tuning, didn't even need a dyno!

Second time Ive used this company in just under 2 and a half years. First time was my mk6 GTTDI went from 140 bhp to 205 bhp. This time I took my MK7 GTD in for the full works It made 187 BHP and 280 ft/lb on first run standard but after the cat/dpf and egr delete she made a whopping 246 bhp and 378 ft/lb the difference is unreal. Customer support is spot on Had a knowledge of info from chris the tuner and Matt the mechanic is a right good laugh.. Couldnt recommend them any higher brilliant.

I would not go anywhere else!
Car drives just like stock but with more power. Chris explained the entire process, answering all questions I had (and questions I didn't have). Very reassuring to say the least. He the pros and cons of various options, recommend hardware based on my requirements/preferences.

Overall I could not be happier with the entire experience, and I will be bringing him more cars to tune in the future.

Highly recommended!

A year ago, I took my Peugeot 208 GTi to Dervtech to get it remapped, and man, what a difference it's made! Before the remap, I’d already added some stuff to my car like a GFB valve, a big intercooler, got rid of the cat, and put in a tougher clutch. I was hoping for a big change, and I wasn’t disappointed.

I met up with Chris from Dervtech, and straight away, it was clear he knew his stuff. We didn't just drop the car off and wait; it was way more hands-on. Chris hooked up his gear to my car, and then we hit the road together to see how the car did. After each run, he’d tweak the map a bit and then we’d go out again to see how it felt. By the end of it, the car was just flying – the torque was insane!

Having this map on the car for a year has been awesome. Every time I step on the gas, the car just goes – no waiting around, just straight-up power, all the way through. Plus, with the limited slip diff, it just grips and goes on the twisty roads, leaving most cars wondering.

Honestly, taking my car to Dervtech was one of the best things I’ve done for it. Chris was top-notch, and the difference in how my car drives now compared to before is like night and day. Every time I drive, it just makes me happy.

Absolutely spot on mapper, tuner, customer service is excellent recently set his new workshop so its a work in progress at his unit currently but still has a 2wd dyno. Recently hes known for mapping mini's and bmw's but ive always known him for his diesel traits, hes currently working on one of my cars and im sure result will be spot on

Huge thanks to Chris for mapping my F56 Mini today.. car feels absolutely mint! Had plenty cars remapped in the past, but first time using Dervtech and genuinely would not use anyone else from now on. Completely new experience being involved in the process too, but that made it so better, especially having each bit explained as he was doing it. Thanks again.

I have had a very long journey today to have my Mercedes C250 diesel to be tuned by dervtech I leave in Kent and I have traveled all the way to Dervtech to get my car mapped and I was 2 hours early for my booking but Chris has took me in and started early and he has done he’s best even I had a unknown problem that nobody including Merecedes main dealer couldn’t find and after all Chris made it worked and find the problem and worked rounded and I am over the moon with the result and now going to fix the problems I got and go back to get more power! 

I would like to thank Chris and he’s other best workers and highly recommend this tuning company!!!

Given that I was new to the whole Car mapping game, Chris made time to explain every stage in detail and answer all the many questions I had. His knowledge and experice is impeccable and outstanding in the arena giving individual condsiderations to each individual job. I wouldn't hesitate in recommending Dervtech and will, in the future, be utilising them again.

I’ve followed this page for a while and have always been amazed with the amount of power they extract from cars. I decided to take my Abarth 595 1.4l turbo to be tuned by DervTech and I was not disappointed. I had added some mods to the engine that needed bringing together. We started at 145hp & 200nm Torque and ended up with a whopping 221hp & 329nm Torque. The car pulls like a train and drives amazing! This isn’t just a generic tune. A lot of time, effort, knowledge and dyno runs were needed to achieve these figures.

Took my Seat here as my average MPG wasn’t great and I also wanted abit more power. They advised me of what power gains I was looking at and also was realistic with my over my MPG. They also health checked the car prior to the re map so we knew the DPF was fine and there was no other issues. Will defo be recommending to friends and using them again in the future for any tuning needs. Over the moon.
