Charlie, if your truck is starting fine, running fine, and you have no issues...why would you tune it?
It's not like the old days when points would wear, or the distributor would shake loose...
The pcm regulates the air/fuel...toss in a set of stock plugs every 10k or so...check to be sure that the wires from the coil packs are not cut, broken or burned...and drive it.
If you just want to get it tuned...get a flash of the pcm...lower the temp at which the fan comes on, keep the lubricants fresh and drive it like you stole it.
The mod bug will bite soon enough...enjoy your truck until it hits...then get ready to sell your soul for hp.
There are only a few trusted tuners for these Viper engines...contact Stinker to find someone near you...I think you are going to be going out of state to find a good one.
