What would you do?
I can speak from experience(b/c i had an 02 with the 5.9) that it def does help to update to better plug wires and cap and rotor..also, i put in ngk iridium plugs in my truck and it ran pretty good..but just like all the other guys are saying, that the Superchips is the best thing that i put on that truck..it woke that truck up like none other..it was the best investment that i purchased for that truck...good luck to ya
Sorry to jack your thread. But I have a diablo sport predator tuner for my 03 ram 1500 4x4 Hemi. I bought it more for gas mileage, but didn't seem to help at all. Now it did a good bit for performance though. My question is, would a super chips be better suited or are they about the same as far as improving fuel mileage? If so I will unmarry my DSP and sell it and get a SC. By computer I get high 11's and lower 12's on mileage. That's mainly around town or towing.

You will be wasting your money. Search the foums here and elsewhere. Basic copper plugs are all you need. You will gain nothing with V power plugs.
Also read a lot of threads and a lot of people recommend the NGKs and people recommend the copper ones for the Hemi which my truck don't have

V-powers are copper plugs anyways. They just have a V-tip for a centered more precise spark contact. Your still getting the benefits from a copper plug. No worries.
