i have a hypertech for 4.7
this is one for 3.7(below)
Spoke to Jet Chips and their programmer will work in our 3.7s
.................with a wopping +12hp and +10lbs torque for stage 1..........+17 hp and +13lbs torque for stage 2. I don't see that as a good deal considering the price tag of $250-$300 (depending on where you shop). The cheapest price I found was $228, which makes it out to be $19 per HP for stage 1. Not worth the while in my opinion, plus Jet Chips has some bad reviews on-line.
SO, I ordered the Hypertech speedometer calibrator to correct my tire size issue and hopefully it will correct my "hunting" for gears while on the highway. I will post up in my garage when I recieve it and install it.
this is a link for one forsale in this forum
works with 4.7 or Hemi.
