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 fuel 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 for shipping! You can call me at 1-800-303-9231 9-5, M-F, or PM me........Bob.
