Can't you just get a PCM from a 07 car from your local pull-a-part? Might as well get a gauge cluster too. I have a 2007 Charger that I am playing with. Bought a used, unmarried Diablo and used the canned tune and it worked nice. Deleted MDS. Then I removed the cats and EGR and got an email tune. No codes. By the way. this is my first time tuning anything.
