RIPP is wrapping up development for the '12+ Pentastar JK's. They decided to handle programming in house rather than the earlier models where they used Diablosport. So yes, obviously, it is a tuned ECU. The programming issues with the Pentastar are the same as for our '12+ Hemi's, they solve it on the Jeeps and it's a short jump to programming the Rams, same electronics. RIPP kit on my JK is complete, as in it comes with the blower, mounting hardware/brackets, new injectors, re-gapped spark plugs, and intercooler piping. They only additional thing to think about is they recommend running a solid catback system.
As far as daily driver issues, we ARE talking about installing a supercharger on a fairly large displacement small block. Here's the good: if you drive it respectfully, you will actually see better fuel economy than stock. You get more power for less throttle input. I saw it in my Jeep, 3 mpg better.
The bad: if you have a heavy foot, you'll suck gas like crazy. Larger injectors, different fuel map, what do you expect?
I should say I'm not a rep for RIPP, I've just had their system in my Jeep for over a year. I wouldn't hesitate to do business with these guys again, their kits are extremely well designed and their customer support is excellent, they've been doing this for a long time.
