I've got an '02 with a 5.3L I have an FIPK and cat back exhaust. I average at least 17 MPG, and I can get 20 or so on the highway if I don't have to floor it very often. This 17 is also a couple full throttle accelerations on it typically too. I think the key is trying to keep the RPMs under 2,000. I accelerate kind of slow usually, but it pays off at the pump.
A lead foot is a lead foot, and thats all i can say.

Hello all,
I'm looking at FIPKs for my 2001 Tahoe 5.3. I was wondering if it's best to go with the K&N or is it worth the extra money to go with a different more expensive brand? The K&N's seem to be the best priced and are available used more frequently. Also, does anyone know what is the difference in the regular kit and the 77 series, other than the chrome pipe?
Thanks,
Brandon
