What year WRX do you have? if its' an 04' then your problem at around 4000 rpm's where the motor seems to hold back is, the stock ECU is switching from closed loop boost to open loop boost... a stupid thing that subaru decided to do on the newer models. If you have an 02-03 i do not know what to say lol.

well.. i hope that kit works out well for you! I wanna see what it does on the dyno compared to the vishnu kit.
