Exhaust, Air Intake, etc

My results are noticeable. It's not a huge difference, but worth it to me.

And my mileage numbers are correct also. I check my mileage on every tankfull and 18 is a rough average over the last couple of months (for highway driving, my city driving is around 16mpg). I fill up about once a week. And I drive 75-80 mph on the highway. I was getting about 17 on the highway but it went up about 1 mpg after I had the pcm tuned.

I have the stock 33's and adventure package. I would imagine with the stock 32's and lower stance of the non-adventure package I would eek out another mile per gallon or two. So I don't think someone claiming 20mpg would be unrealistic. Steve, you should try a pcmforless tune, you to could then enjoy the many benefits!
