Dodge Durango Forum II Dodge Durango Forum IIMopar does not have a PCM for the R/T models yet! I have '99 5.9 2wd that i have put a PCM on and I can feel the difference. I do run 92 or better octane. I tried a tank full of 89 Octane and noticed slight pinging at wide open throttle.

There is a Pcm available for you 4.7.
