This has happened to me before with a previous car and as it had REVO, a local agent sorted me out FOC. No hassle, no cost, no travel. At the time it would have been an expensive headache had I of opted for CC, or others for that matter.
Maybe CC have changed the rules now?
Also looked at GIAC but couldnt didnt fancy driving to Scotland for the pleasure.
IMO there isnt a great deal of difference between versions of Stage 1 software.
You have to pick one that you have confidence in, is convenient, and has the power delivery that suits your tastes.
Ive also had the REVO trial (twice), both times it made a significant difference. Enough to make me cough up Ł500 for the full code which was better again.
Cant undertstand why your trial `didnt work`but it matters not if you have an alternative map which suits. Its clearly jaded your views of REVO enough to write them off as a reputable performance software outfit.
Anyway, the message is, `Dont leave your S3 standard`, its a waste.
