And is that 3mpg hand calculated or by the computer? I can lift two of my toes off the accelerator pedal and bump my mileage up according to the computer.
Now a new y-pipe I'm sure will help out with power.

I'd like to see what the MPG difference is when the truck is tuned, both stock exhaust and modded. It *seems* that most hardware upgrades make the biggest improvement on a stock-tuned setup. I gained about 2-2.5 mpg avg going to my LMS 91 tune.....if I could squeeze a bit more with exhaust....I'd do it.
