I'm going to try the exhaust system and the Hypertech programmer and see what happens. It sure feels sluggish with the bigger tires too.

So much for paying attention. Go buy a Turbonator/Spiralmax/Shredded Beercan for the best milage improvement. Or just pull 4 ignition wires so you to can have the Caddys displacement on demand.

Re: Gas mileage improve?
Lame? No, whats is some rookie coming in here and asking about gas mileage. Hint, use the "SEARCH" feature. I think you will see that this topic has been covered 1 or 2000000 times before.
Also may want to go to a dictionary and look up the word SARCASM.
Now, send me $5.00 and I'll tell you how to get 28mpg +.
