Just what I needed...
I'd added a K&N FIPK, a JET Throttle body spacer, JET Performance module and a Flowmaster muffler to my Trailblazer and still was missing the OOMPH. My wife ordered the JET M.A.F. for me and that was just what I needed! The truck has great pick up and sustainable power. The throttle response is also greatly improved. I'd recommend it to anyone with the same or similar vehicle. Thank you JET Performance.
The installation process would have been much easier, had all of the necessary parts been shipped. Having to purchase parts from a local hardware store that were missing from the package put a damper on the entire project. Having said that, I can definitely notice a difference in performance. Engine RPMs are lower, gas mileage has seemed to improve and the motor has a subtle, but notably deeper sound.
