I just purchased an 03 5.7 HEMI and I don't know anything about "tuning," where can I go to get easy to understand explanations of the different chips and where to purchase them etc?...

 

At the top of the page should be a tuner thread....there are two one for SuperChips and the other for Diablo....they both work good and each has a few differences.....but until you get one do a search for the TMR delete mod....you will be glad you did...takes only 10 mintues...
