id think twice mate ... ive had REVO on 3 out of my last golf mk4 18T's ,,, and i found out from a good source that your car does not actually go back to ITS standard settings affter the trial, its a standard setting that REVO have set themselves. Also, REVO gives u a good whack of torque up to about 5k revs then eases off .... so then wat ?????? hmmmmmm im a bit pessimistic about revo now dude.. it all seems good at the start. also, you got to think, REVO is a GENERIC map, which is not tailored to your specific setup. whether standard or not, every cars different. the same REVO file is uploaded to any petrol 18T.
This is when ppl like Custom Code and Performance Torque come into play, where (for less cost) theyll tailor the map to suit your specific car!!! I seriously recommend you look these guys up before u spend over 400 quid...
regards.
