Were the 14 warranty claims on your gti all engine and drive train related? If yes them I'd be staying well clear of revo as you're not the first to have such issues.
Flywheel, clutch, gearbox and inlet manifold were all drivetrain after the map, but I'm 90% sure the clutch was slipping before the map. What about a tuning box from DTUK?
I'd recommend a DTUK tuning box - whilst the outright gains might not be the same as a remap, the strain on the components is also reduced accordingly. Got one on the GTI and love it!
