Customer Feedback

What the customers say

★★★★★
"Came out to the farm near Lairg — didn't need to move the van at all. The difference with the trailer is significant. Better fuel down to Inverness too. Very impressed, wouldn't hesitate to recommend."

★★★★★
"Two other garages couldn't sort the DPF warning light properly. RAP Remaps found it first time and fixed it on the spot. Honest about what was wrong, no unnecessary parts, van back on the road same day."
SC

★★★★★
"Excellent knowledge, no hard sell. BMW feels completely different on the A9. Explained everything clearly, and the car has been totally reliable since. Great service and a completely different level from a main dealer."

Our Promise

What You Can Count On

We've been doing this long enough to know that trust matters more than any headline power figure. Here's what we stand behind, on every single job.

🔄
Full Return to Stock
We always keep a backup of your original factory file. If you ever want the vehicle returned to standard — before a dealer service, a warranty check, or for any other reason — we do it. No charge, no quibble.
🛡
Safe Limits Only
We don't push engines to their absolute maximum and call it good. Every calibration is written within safe parameters for the hardware fitted. Reliability for vehicles in daily use matters to us more than eye-catching numbers.
📞
Aftercare Included
If anything doesn't feel right after we've left, you call us. We don't disappear once the job's done. Most issues are sorted over the phone or on a return visit — we stand behind our work, full stop.
