Just got the tune applied today from DRD, dealt with all the exhaust stuff, and all I can say is WOW!!!! I can really feel the cummins pull in the higher gears like it should. I will need to keep it on the stock or tow setting for quite a while until I can afford a stronger clutch.

One question, does anyone know if Rays tuning sets the exhaust brake on automatically? Mine does not seem to.....I thought I read that somewhere that once tunned it would automatically be on at start?

Next up is the engine stuff, guess I need to get a bigger box to store all this extra hardware that the EPA makes RAM put on these trucks!
