Went GIAC. Very impressed. Actually expected more power but I am so pleased with the sophisticated feel that the modest incease in HP and torque is not an issue at all. I expected only a subtle incease in power (but secretly wished for more).. What I did not expect is the smoothness of the ride now. After the full millitek exhaust and the hyperflow intake were installed, there were soft spots in every gear under 3500 rpms. Now that is gone, and the sweet aspects of the car are a little sweeter. The most noticeable and most pleasing difference is that there is less of a need to downshift. If you are coming up on a redlight in third gear at 3500 rpms and take your foot off the gas - the bottom would drop out and the rpm's would fall precipitously. Now the car 'holds the rpms' tighter AND throttle response is better.
Overall very impressed with what feels like a high quality, sophisticated product. I love my car even more now. and that's what its about.

 

Don't feel bad there is always the 30day refund policy. If your happy then great for you but I would be pissed if I spent all that money and all I could say was it was smoother.

You might also want to look into the intake the hyperflow has been proven time and time again to not help power wise but only to suck in hot air.

If the chip and the intake lost you 5hp but you are still happy then in the end that is what it is all about
