Keep me updated!I plan on getting some tuning done to mine at some point t. I’ve heard that helps a lot. My buddy just had his 6.4 rebuilt and is doing tranny tuning now. He seems to like the changes that are happening.
I know the gearing in the trans will never change and it is kinda fawked up for a hemi, but i think with some tuning it could certainty be a lot better.
