This has been discussed many times before. The Jet Performance chips 1 & 2 are not worth it. The Mopar Stage 1 is programmed for the car perfectly and is the building block to more power.
If you have a stock engine with no other modification, this is the chip for you.
That should give you a clue right there. Add more performance parts to your car and they will be worthless to the Jet chip, both 1 & 2. If you don't believe me go here and ask. Lots of PT gearheads here.
