What Customers Say
“Five star service from start to finish. I would highly recommend. Friendly and professional.”
— Kieran Brennan
“They came to me, too — was very helpful. Would definitely recommend them.”
— Natalie Sands
“Today these guys did a Stage 1 tune on my 1.5 dCi Nissan Qashqai. The difference is night and day. They really know their stuff. I tried a couple of other companies before these and their tools couldn't tune my car, but for these guys it was no issue. Thanks so much. 100% recommend.”
— Tommy Kilvert
“I had my 2007 Fiat-based Rapido motorhome remapped as it wasn't performing right and the fuel economy wasn't good. They informed me the vehicle had already been remapped, so we decided to remove that and install a new one. It was absolutely much better — excellent acceleration, no sluggishness on hills, and fuel economy improved by another 5 mpg. Very pleased with the results and highly recommend.”
— Ricky Rowlands
