Thanks for the input, it looks like Pac Brake is going to make $1,400 off of me.

Can the predator do anything that will act like an Exhaust Brake? I have a 2005 with an automatic. I know some tuners can do it on a ford, just wondering about the Dodge. Thanks

Thanks again

Thanks, one thing I was wondering about was the fact that I do not have an EGT gauge.

What changes does the tow mode make? I have an 05 automatic with 190k on it and I do not want to toast anything. I pull a 13k 5th wheel and the truck handles it just fine, but more power is always better. I have a tranny temp gauge, but that is it. I have put every mile on this truck, so I know it ...
