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.

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.
