Ok just has studs and egr delete put in and the dealer decided to put a cold start update in the truck and now im geting 14 mpg and it just doesnt have the power like it used to have. I run erics extreme race and its just not there. The only other change is I took the stacks off and put 4" duals with a muffler. I cant believe the muffler has made it that slow what gives? was it the cold start update? Im planning on doing ficm tuning soon.
Well just checked the strategy and its the same. Im lost, my wife says its just not as loud cuz I dont have the stacks so it doesnt seem as fast. I dont know Im gonna order a new tune from eric and see if that changes.
