The only other thing would be a SCT tuner or SuperChips tuner. Other than that you would need to tear into the motor, and these motors get expensive very fast to build.

That's unfortunate. I had a diablo 3 I think it was called. For some reason though when I tried programming it, it would never fully program and then go back to factory settings.

Brand new. Got it from super chips. Had the correct year and engine size of the jeep and the diablo is what they recommended me to get

Basically it just became another fuel and gas gauge. So I returned it.

Re: 08 4.7 grand cherokee

Diablo and super chips are two different companies. Can you give me a model number for the handheld you bought?

Re: 08 4.7 grand cherokee

That should work. Maybe you got a faulty one.

I called customer service to have them help. I didn't everything right they said, but they also told me to get a new battery. They thought maybe the chip was not getting enough juice I guess.

Re: 08 4.7 grand cherokee

If you have a 08 4.7 diablo Does not support it I don't think. I have a 09 4.7 and I have superchips 3875 which is now 3870 or 3860 now. Im running the 91 perf tune with the trans app. It is an improvement over stock for sure
