OP, don't listen to all the people in here talking trash to sell GTM products. Notice how they have no real suggestions to help you, they just want to criticize the stillen kit and bring you down.

I am planning on getting the 928 Motorsports impeller soon. I think it will add a lot of midrange torque and some high end power with the increased volume. I wouldn't be surprised if PSI went up due to the flow. Probably bump me up to 470whp.
RCZ is right. I have no complaints from my kit and my review speaks for itself. I just wish I lived closer to sea level! I am hoping to be able to replace my 9PSI pulley and get up to 8 PSI of boost at altitude. I am currently trying to determine what RPM the blower is turning with the 9PSI pulley to see how close I am to the 52K upper limit. That 928 motorsports impeller also looks promising but would cost a bit more than a pulley swap.
