So yesterday (sat) I finally installed my Invidia Catless DP and flashed the Perrin Stage 2 map on. Wondering cause around 2500-3krpms under low accleration it makes like a shuttering sound. don't know if thats normal or abnormal... car funs fine its not an exhaust leak just wanted to make sure the shuttering sound was normal

which cat back do you have installed? Also, I was under the impression that Perrin St.2 map was very specific on which DP you could run with it. Perrin is the only dp with "2" hi-flo cats plus a seperated and divorced design. that could be your problem
