My cousin has an 07 Ram 1500 w/ the 5.7, and he's just finished putting on exhaust and a CAI. His friend who used to own a performance shop custom fabbed the exhaust, and it sounds great, but its throwing a check engine light, and the O2 Sensors are fine. It also has a rough idle and lurches when he has the cruise control set. I'm thinking the exhaust isn't giving him enough back pressure, and he needs to pull it off and put on a name brand kit that has already been tested to work on the truck. He keeps thinking his friend can fix it. Now, the guy he bought the CAI from is trying to sell him a Bullydog programmer, saying that it will fix any problems in the truck.
So should he replace the exhaust, or try the programmer? Would it be as simple as just putting a high flow cat in the truck? He still has the 2 main cats, but he removed the 3rd cat to put in the H pipe. Also, if you known any HELPFUL Hemi forums, list them. I don't feel like searching and trying to find a forum that won't tear you apart for asking a question.
