What Devon drivers say after a remap with Auto-Cleanse.
Had my 2018 Audi S4 Stage 1 remapped by Auto-Cleanse and I'm genuinely impressed. I was a bit unsure at first because I wanted the extra power but didn't want to risk reliability. They explained everything properly, checked the car over first, and made sure I understood what the map would actually do. The difference is massive. It pulls so much harder, especially through the mid-range, and overtaking feels effortless now. The car still drives smoothly day to day, just with a lot more power when you want it. Really professional service and you can tell they know what they're doing. If you're thinking about getting a Stage 1 but you're worried about safety or reliability, I'd definitely recommend Auto-Cleanse.
Had my Renault Trafic 1.6 remapped by Auto-Cleanse and honestly the difference is night and day. Pulls much better, smoother to drive and feels far more responsive, especially in lower gears. Tom carried out full diagnostics beforehand and explained everything properly before touching the vehicle, which gave me confidence straight away. Proper professional setup and quick turnaround too. If anyone is looking for ECU remapping in Devon I'd definitely recommend Auto-Cleanse. Top service from start to finish.
Just wanted to say a massive thanks again from Auto-Cleanse been in today to get stage 1 and added burbles on my ford focus st mk3 couldn't be happier car drives so smooth and I love the pops! Cheers 💪
