Not a plug in chip, just a hand held tunner. I'll re-tune and see what happens, see if there's a setting.. Didn't see one? Changes are possible, I can set certain things, didn't see an idle setting in park, I'll try again tomorrow. Put it in gear and it's fine! Exhaust is not touching, it's reverbation in the cabin, straight through baffels not chambers like Flowmaster. Like the old time glass packs. Don't think the 4.0 is smooth enough enough w/out them. Like I said the original set up had vibration damperners... a strange set-up! Never knew what those things were till now, now I know.
Bassani is no help, but I going to have a talk with one of the Engineers.
Thanks, See you at the WinterNationals!
