can anyone please tell me the name of a chip hat u put into ur truck it gives u additonal HP, i saw it on Car&Driver television.

go with Superchip. They kick ass. My bro has one for his 01 5.2 along with a kandn fitercharger system and flowmasters. It made a hell of a difference. Depending upon the year of your truck it may be a chip or a computer type thing that you plug into the port underneath your dash.

you can also use the Hypertech power chip . you can find it at http://racingparts.streetracingshop.com/?x=161&y=52
I have a friend that uses it and it did wonders !! you can change shift speeds, set it for what size tires you are using and many more options !! see what u think !! Tom

Mopar also makes a performance computer for years up to 2000.
