I have a stock magnum with the hemi engine. Has anyone tried the 1st stage jet performance chip module ? Do you notice any performance difference? Does it help some with gas mileage? Is it worth the $250.00 cost to purchase? Thanks for the input.

I have the Jet Stage II chip and the Superchips programmer. The Superchips programmer does a lot more, but Jet boasts of more HP. I did notice better gas mileage and performance with the Jet, but the superchips has other features that have made me use it instead of the jet. I am selling my Jet for $150 if you decide you are going to purchase one

 

i have just the chip. and love it. i have had no problems with mine. i can tell the differnce with and with out it. very easy install and i got a great price off the net!
