Daveo,
I am really happy with it. I have my tune perfect now and its making quite a lot of power at 14 psi it makes 204rwkw and I can't run anymore than that till I get new coilpacks. I have just ordered splitfires and will get them over the next few days. then 18psi will see 230rwkw. Last time it was on the dyno it made 220 on 17psi but was missfiring all over the place.
In short I have not had a single problem, drivability is great and the acceleration when it comes on boost is nothing short of JEEBUS!!!
