V-Power!
As far as the Stage 1 Remap goes, I've had 3 now over my two Mk5 GTi's.
One PDT carried out @ Storm Developments, Aldermaston, 1 of Storm's own maps on my new Laser Blue, and now I'm on Revo Stage 1, again done by Storm. The only reason I went Revo was because I went in for a free upgrade of Storm's own software, but my ECU would not allow it to over-ride the existing map, and the car refused to start! My onl option was to go Revo, because their tool wipes the software completely rather than trying to over-ride it. Is the Revo better? Probably marginally, the PDT and Storm maps are excellent, but the Revo is no way double money better! £600 as opposed to £300!!
I'd have stuck with PDT or Storm if I could have, but my ECU was having a hissy fit that day. I suspect VW did something to it when I took the car in for fitting of new door trim. B'stards!
