you feel a little bit of power.. just ease off the accelerator a bit and you too will notice the mpg increase a bit. do recommend it!

good product, hard to tell a difference. combined with a cold air intake, low restriction exhaust and a jet performance module, i would say its a good buy. by itself, probaly not worth it. overall i'm stoked cause it all ads up to equal more horsepower.
