I'm trading in my 05 Ram 1500 5.7 and won't be needing my jet module! It's a stage 1, which is optimized for stock trucks, so you can burn as low as 87 octane. (Use premium for best performance gains.) I still have the original box and instructions. Installs easily! These sell for about $250, I'm asking $125, and I'll pay the shipping! You can call me at 1-800-303-9231 9-5, M-F, or PM me....Bob.

 

Will this work on an 06? What does it do for your mpg?

 

Yes, the #90406 will work on your 06 5.7! You can check out the product at www.jetchip.com. I installed the chip as soon as I got the truck, and I have a lead foot, so I really don't have any economy info. Check out their web site...DacotahLeather.
