RIPP Diablo Intune RM3000NA HEADER Tuner

I got it with the headers for a 2007 jeep jk

Cleared up the DTC complaining about the catalytic converter, which had been on for over 3 years (after installing the headers). Plus, there is a noticeable change in performance.

I started with installing the long tube headers and cat back exhaust, which was WOW a great improvement on my jk 3.8’s performance. Now I have flashed my pcm with the 87 octane map. I did see some performance increase, but what I am most impressed with is shifting patterns of the transmission, and throttle response. I don’t care what anyone else says, the Ripp long tube header, cat back exhaust, and Diablo retune brought new life to my 162,000 mile jeep jk 3.8 drivetrain.
