I was considering supercharging my truck and then realized I would have to start defecating quarters to do that. So a friend suggested that I get a new performance chip instead. Does anyone have any information on any really good performance chips? Or any other way to give my trucks some umph while keeping my gas mileage in the double digits?

 

Go with this order:
Airdoc cold air intake http://www.airdocintakes.com/product_three.htm
Exhaust mod of your liking
and than get a pcmforless tune http://www.pcmforless.com/index.php?...per&Itemid=319

 

Might be nice to know what truck you have to be able to answer your question.
