You guys that have the blowers/turbos right now are you using the tune provided by the manufacture or are you having a dyno shop do a custom tune? I have a 68 Pontiac Firebird that I switched over to EFI with a blown LS3 and had a custom tune done by my dyno guy. Not sure if his tuning program supports Chrysler/Jeep he does a lot of Mustangs, Camaros, vettes.
