I just spoke too revo today for feckin ages, and now have a better understanding of the hard ware required and what revo recommend.
The guy i spoke too seemed really clued up and genuinely passionate about GTIs, he might of actually had one i should off asked.
i got loads of great info and recommendations on which parts work best with the GTI, He recommended the intercooler for stage 2 and said that ideally he would fit it even at stage one, he has also seen amazing results with the ITG intake with one ED 30 making 40bhp and the normal K03 making 20bhp which he said he was shocked at, although this wasnt a one off as it has been repeated numerous times ! He also said that the Blueflame choice was a good one, and said it was a cracking system with the best gains ! he did also say to me that if he was going as far as im going to go that it would be best to go for the HPFP, not because of any reliabilty issues of ill running but only because of the performance gains in the mid range where the stock pump FAILS to deliver the goods, I still dont think i want to go down the road of an HPFP so ive settled on
1)VW piston Divertor
2)ITG
3)s3 intercooler
4)blueflame TBE
5)revo stage 2
He said that was a good spec and was what he would go for if it was his car but with the addition of an HPFP
