I saw some advertising on a tuner from Jet for 2011-2012 Ram 5.7. I called Jet Performance in Huntington Beach, CA (800-535-1161) and spoke to customer service (Corbin)and was told it is a piggy back unit. It is not adjustable and plugs in between your harness and the Ecu. It delivers a HP increase of 14 rwhp and 16lbs torq. on 91 octane.The price is $319.95.
I have tried these piggy back units before and was very dissatisfied with the performance gain.
I think we will have to wait for Diablo, Hypertech to develop an adjustable unit.
