Exhaust, Air Intake, etc

[tomp]

Volant CAI is the only intake choice for me

Either Volant or Corsa exhaust

NO on the throttle body spacer! Doesn't make sense to open up the intake & exhaust for more flow, only to then restrict it down with the spacer

I checked the numbers I went 242 miles and filled up with 20.5 gallons.

I did change the tires and wheels on the truck though. I went from the stock 18's to MotoMetal 18's with 33x12.5 tires though.

Also to those that did these mods..are the results noticable

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!
