Had my transit custom remaped here absolutely night and day difference in the drive. Quality customer service definitely recommend.

- Alfie B (FORD TRANSIT)

Having taken time considering whether to have a re-map, I took the plunge and chose RPM Sussex. I only wish I had it re-mapped sooner The performance of my 10 year old Juke has improved better than new. RPM Sussex, made the work quick and easy. Having booked a time convenient for me, it took 1.5 hrs and looking at the stable of prestige cars being worked on by them I did not have any worries. Work done, RPM walked me through the before and after results.

Mercedes B180 Sport stage 1 performance remap done for me at RPM, Had issues with the standard remap with car cutting power when TC Kicked in but RPM took car back in to run a diagnostic and a new custom map was written to address the issues which seem to of done the trick as Now get full power ALL the way through even when TC kicked in, the car now pulls like a train.
