Thanks very muchZac FrostZac Frost ★★★★★ They did a cracking job, would definitely recommend!Dan TrotmanDan Trotman ★★★★★ Had my transit custom remapped, excellent service, totally transformed the vehicle, will be back with the touareg at some point 👍Andrew MatthewsAndrew Matthews ★★★★★ I would highly recommend Somerset Tuning, after my car went into Mercedes for a recall they did a software update on the engine ECU and the engine management light came on and they refused to correct it. I brought my car here and after scanning and diagnosing the issue the ECU software was replaced and the engine management light was off. On the drive home the car was faultless the engine was more responsive and the throttle pedal delay I previously had was gone as well. I can’t recommend them highly enough a superb service.

The car now roars with a power and smoothness I never thought possible.Martin’s genuine professionalism and warm friendliness made me feel like more than just a customer, he understood exactly how much this means to me. He took the time to explain everything with heartfelt clarity, patiently answering every question, making sure I felt confident and cared for every step of the way.The process was faster than I imagined, and I was deeply touched that he didn’t cut corners and running full diagnostics both before and after to guarantee perfection. It’s rare to find such dedication and passion, and it’s clear Martin truly cares about delivering the best.I cannot recommend this enough! If you're contemplating a remap, do yourself a favor as this is the place where your car’s true potential awakens.

Made a massive difference in power and torque. Would highly recommend!!Jock HedderwickJock Hedderwick ★★★★★ Mercedes CLK320 cdi stage 1 remap. Martin first meticulously checked the programme to check for any previous mods then installed the new programme then disabled the swirl flaps and EGR.I then test drove the car with Martin continuously monitoring the programme parameters during the test drive putting the car through its paces.Very impressed with Martin's attention to detail and thoroughness as well as the way the car drives. It feels much more willing on the throttle, more responsive, more power and torque with smoother gear changes (it's automatic) and even a slight improvement in mpg. Well worth the money.Alexandre LopesAlexandre Lopes ★★★★★ Martin is a great guy, contacted him for a quote and answered the same day,showed himself 100% available and was really easy to book with him, great and quick job,car came out pulling really good, recommendedMarkMark ★★★★★ Martin came out to us with his wealth of knowledge to re-map our Honda Estate.
