lol so true. this is partially why my catless DPs throw CEL. whats annoying is that ever since i have installed my DPs, i go into limp mode almost every day or every other day at least. i also have procede v 1.47.

do you guys think its the catless DPs causing the limp or is it that i might just need a tune? both the CEL and or limp happen randomly.
