Installation was easy, the product looks great and had all the hardware for install. Took about 30 minutes. No wine noticed under acceleration. Feels like it has more throttle response. I haven't driven it enough to check the fuel economy.

This is the second one I've had nad they work for MPG, the first one was on a 99 Suburban 4x4 with a 350 and I went from 16 MPG to 22 with it and a cold air intake and a complete tune up. These are so simple to install that even a novice can do it. I would but again if the need arises.
96 Tahoe With New Engine

Installed Helix on my 96 Tahoe at the same time I installed new engine and fuel injection. Noticeable improved low and mid range throttle response. Seems to be more torque/horse power from standing start. Mileage seems to have improved, but engine not broke in yet. Would reccomend.
