I have had it installed for just over a week now and I definitely can tell the improved throttle response. I haven't seen any improved MPG. As for horsepower, I have this installed with the aFe cold air intake and overall I feel more horsepower, but not sure which item really provided the additional horsepower. I purchased because I wanted more power for towing and better MPG. The better MPG is yet to be realized, but I would still recommend to others given the relatively low cost and increased horsepower.

I found that two of the hose clamps were not large enough I had to purchase two additional clamps to complete the install. I have only seen a small increase in the performance and very little increase in fuel mileage.

I bought the Torque Booster tube and Pro Dry S Air filter and here is what i thought. Pros: Filter-great fit and no prolem with it at all. Doesn't need to be oiled. Intake Tube-Look stock. Sounds great. Quick and easy to install. Cons: Intake Tube- Needed to be cleaned on the inside because there was debris in there. There's no bracket for the radiator hose. I installed this on my 2008 Chevrolet Avalanche LTZ with the 5.3L Flex Engine.
