Well the Superchip didnt work in my truck I sent Superchip the files they needed and after a couple of days I called them for the fix and they told me I have to wait for a phone call.. I called back the next day they told me maybe 2 weeks I would have an answer and were really rude. I had it returned and ordered a Diablo inTune, after trying it for 2 hours it didnt work and got stuck in the loop of rebooting.. I called Diablo and in 5 minutes it was unlocked and the car took the tune... It did wake it up a bit but the transmission still wasn't right. I contacted Sean at Hemi fever about my concerns in an email. Today he responded and said he could help me. I paid for the tune and within a couple of hours he sent me a 93 Octane custom tune. I installed the custom tune and let me tell you this truck is running awesome , and the transmission is spot on. I just installed this morning a K&N Cold Air Intake. Sean at Hemi Fever is awesome I highly recommend him. He asked me to also send a log with certain PID's so he can see how the Jeep is running.
Even though the Jeep isnt my Trailblazer it still has the power I expected out of this Hemi. Now I am totally satisfied that I bought it..
Note: Superchip still hasnt called about the tuner its been 2 weeks.
I think Diablo is the way to go even if you dont get a custom tune.
