Go Revo. I am looking forward to getting my Pirelli dynod after trying a Forge twintercooler with stage 2, it was 300 hp at 6k but wouldn't pull beyond 6.5k and 320lbft of torque from memory at JKM. Back to simple stage2 with just Revo chip, TBE, filter and forge DV it is miles better and pulls much harder to 7k so I have no doubt it's 300+hp on modest settings for timing and boost.
Revo were very helpful assessing the issues and testing, all free and I simply removed the Forge twintercooler. They had experienced inconsistencies with them, so I removed.
You get what you pay for I did have a cheap map and it was crap .....
