Excellent service . Would definitely recommend.Jason SJason S ★★★★★ Martin and his unit are tucked away off the beaten track but the effort to find them is totally worth it.There was a slight mix up with my booking, but it was no problem at all and I was accommodated in the agreed time frame. Martin is clearly very knowledgeable and takes time to check the vehicle thoughly before starting the remap process. As for the results of the remap, wow! My Volvo is 18 years old and was starting to feel a little underpowered but now it is transformed. Martin offers various services and whilst I was with him he took a call from a customer who was having ad blue issues, and had been given duff information by other garages. Martin took time to explain the likely problem and best course of action, without any hard sell or rubbish!I would highly recommend his services.Steven MastersSteven Masters ★★★★★ Absolutely brilliant service! From Martin quickly contacting me after filling in an online form, answering any questions I had, with a wealth of knowledge, and finding a convenient appointment to fixing the problem quickly and easily. During which time I felt that my car was in really good hands with Martin’s professionalism and highly technical equipment for the job! Within no time my car was fixed and running smoothly again.I thoroughly recommend Somerset Tuning and will definitely return whenever the need arisesLee ShephardLee Shephard ★★★★★ Martin quickly and efficiently sorted a problem with my BMW E46 330ci clubsport within hours of me contacting him. Really nice bloke and would definitely recommendJames CooperJames Cooper ★★★★★ Absolutely incredible service, feels like driving a new car.Martin is amazing and really knows his stuff and has all the equipment to make the whole process so smooth. Whole stage 1 done in 1:30 including test drive and alot of me asking questionsJake McDermottJake McDermott ★★★★★ I had my Audi Q5 mapped, with the AdBlue removed and the start/stop system turned off by Martin. He was very professional, clearly knowledgeable, and took the time to explain everything throughout the process. He even came with me on the test drive to make sure the car was running exactly as it should.The car now drives how it should have from the factory—much smoother with a far better and more consistent power delivery throughout the rev range. I’m really pleased with the results.Thank you very much, Martin. I’d highly recommend him to anyone looking to resolve issues with their vehicle or safely increase performance.alan mycockalan mycock ★★★★★ I have just had my Mercedes GLA tuned by Martin and WOW what an improvement, the drive and exceleration has improved, but the biggest improvement is the automatic gearbox, gone is the very slow and lumpy gear change to a fast and smooth change, I now have to look at the dash to see what gear I am in.I wood recommend Martin to anyone thinking of having a tuneup.Thank youAndy CrokerAndy Croker ★★★★☆ Very good,knowledgable will use againJordanJordan ★★★★★ Modern day hero. Had Ad Blue issues ongoing with van until i took it here. Went above and beyond to accomadate me and got the van back on the road quickly, reccomend to anybody, Thanks for the fixCallum MaynardCallum Maynard ★★★★★ Amazing bloke top man best tuning around definitely will use again 👌🏻Samuel TottySamuel Totty ★★★★★ Fantastic service. Martin is clearly very knowledgeable and the remap was a lot more involved than I thought - not just a plug and play and take the cash job. Martin looked at the current setup, checked for any pre-existing issues, applied the remap and came for a test drive while monitoring live data whilst I driving to make sure the remap had not caused any issues with the boost, fuelling etc. The outcome of the remap is spot on - a lot more responsive and power where you need it when driving on the road.
