No, not with Remaps UK. Our custom ECU remaps are carefully developed to improve your car’s performance while staying well within the limits of its components. We use tuning files developed by JF Automotive in Kent, designed for safe, reliable results.

Some companies chase high power figures by pushing engines too hard, which can strain the engine, transmission, or cooling system and cut down on reliability over time. At Remaps UK, we focus on balanced tuning that keeps your vehicle dependable. You’ll get noticeable power gains without putting your car at risk.

If you’re not satisfied with your Stage 1 ECU remap from Remaps UK, you can request a refund within 14 days of the tuning date. You’ll need to book a time for us to revisit you and remove the remap. If there’s no issue caused by the tune itself, we charge a flat £50 fee for this visit. Once we’ve restored your vehicle to its original settings, we’ll refund the full cost of the remap.

Refunds depend on us removing the tune—no refund will be given otherwise. This guarantee only covers Stage 1 remaps and doesn’t include services like pops and bangs, parts, or dyno sessions. If you bought a modification that needs the remap to work, only the tuning file cost is refundable. We reserve the right to end this 14-day guarantee at any time.
