Does any one have a 09 4.0 with a tune in it and did it help any.

Does it have to be a 2009?
05-15 4.0L are the same.
@kp.taco has a 2009

There's the one tuner from OV Tune but that's about it. I don't know if it's any good or not.

This right here.
Or u can try the maf calibrator which has been shown to give 15hp on a stock truck with proper tuning.

Ucon is another route but ur gunna pay alot more, and have new exhaust cam gears, therm, and other stuff to go with it. It will have remote support for tuning tho.

Then again, anyone with a supercharger has a "tune" as well... It's just not custom.
