The tuner was great for correcting my speedometer for larger diameter rear tires. The Tow-Haul mode works pretty well, keeps you in gear longer and gives you some engine braking. I get about 14.5 MPG in town and close to 20 at 70 MPH. I also have an AFE CAI and an AeroTurbine muffler.

Also I run the 91 oct tune normally 04 5.7 and I have noticed that my tail pipe is black; do you not notice that with the 87 tune?
