I have a stage one AUM on a revo remap, completely transformed the car pulls like a train now! Got it done a few weeks ago on 27K miles, also fitted a 008 valve. Got it done at Falkland performance, would highly recommend them great garage. The performance of the standard car wasn't fantastic but after the remap its scary till you get used to the acceleration

. definitely worth it much more responsive on the motorway than before and pulls hard anywhere in the rev range above 2K.
If you are going for a remap the common issues afterwards are coil packs failing- apparently easy to fix, MAF failures- a bit more expensive, hose leaks - more of a pain than anything else.
Overall totally worth it
