My buddy has a 05 4X4 with a bullydog with crazylarry installed. recently we were coming home from hunting and when he would let off the gas when the truck had a load on it (going up hill or speeding up rapidly) there was a noise that sounded just like my VP 44 studdering when I let off fast with my TST comp. Only difference is that his truck didnt shutter like mine does when I do that. Could it be his CP3 just shuddering like a VP 44 or is it going out? He thinks it is his turbo, but I dont think it would make a noise like that. What else could it be?

 

sounds like your talking about turbo bark
and stock units will do this

 

sounds like turbo bark, not good on a turbo
