i must admit i did consider Revo after doing a bit of recearch and may consider Revo stage 2 or GIAC once i fit a turbo back system and new fuel pump
For a stage 1 remap without any other mods i just don't think either are good value
in the glasgow area there is the choice of Revo, CustomCode and ChippedUK and i had previously traveled to Kirkcaldy to Starperformance where i had a custom map done on my MK4. Starperformance are no longer APR dealers, instead they are now GIAC providers and Jim up there really rates them.
I had phoned my local CustomCode dealer 2 or 3 times just to get to speak to speak to their guy as he was never there, i was then told that they'd need my car for about 3 days as they had never done a custom map before

, pity because i've read only good thing about CC but ruled them out because of local inexperience
At a RR day at Starperformance last month a MK5 gti DSG made 249bhp, 270lb ft with only the GIAC and no other mods. My MK4 AUM was the highest MK4 of the day with 236bhp, 270lb ft running a stage 2 ChippedUK map with turbo back Jetex, K&N panel and SFS TIP, this is why i had no qualms about getting my MK5 done by ChippedUK and for £300 think it's good value all be it after a second attempt
i am looking forward to the next RR day in my area to see what the new map makes
