I have a 2003 dodge and i have the rkl tunes on my predator and i have been running one of the tunes and my truck has had no issues. Now i have installed a puck without using the puck stack tune. Then Brought it back to the dealer i bought the predator from and he put a different rkl tune and now i have a very loud clatter like and older dodge. Its REALLY noticeable when its could and hasn't warmed up yet. once it reaches around 160-180 its drasically reduces but still has a clatter louder than the truck has ever before. Is this going to damage my truck, and what do i do about it. i have had three diffrent replys. please help. thanks

My does the same with rkl tunes. I'm going to take a stab in the dark and say that the rkl tunes are hot, timing and fueling is agressive. How else is it going to make 150+hp on our 03's? I think it's normal.

I'd go back to the same tune you ran before that was good, or try some of the other custom tunes available here.

You are correct... the timing rattle will get loud after a certain point... just make sure you watch your EGT's and rail pressure... drop to low youll start rail pop and burn up your cp3...
