differences being Greddy IC's, and I have a lightened flywheel but no lightened pulley, I also am on a JWT ecu. My AVCr is set to 1 bar max (14.5ish psi?). I should hit up a dyno and see what the car actually does, I just assumed it was significantly less than that fom seeing many other cars more modded than mine put up around that or slightly less.
