My first mk6 in 2009 ran REVO and hit 260bhp on the rollers and 299lb ft stage 1. It was an animal when you wanted but did suffer excessive wheelspin and quite a bit of torque steer (running non standard wheels).
My next GTI was on Bluefin as it was reportedly much tamer and is a bit down on power from the REVO but much more civilised to drive. Much more like the standard car but with more power everywhere and no nasty torque spike at low RPMs (although torque spikes can be massive fun when you're in the mood!!!).
The mk7 is quite new yet and I haven't seen many remaps launched. Abt do a piggy back ECU and claim 300bhp straight out of the box which would be amazing, and DTUK do a tuning box which they claim adds another 30bhp.
