ok , i think im just going to strait pipe it , i live in michigan so we can pritty much get away runnin open headers . whats really confusing about the truck when it does its loading up thing , is it only happens once in a while . i drove it for about 6 hours yesterday , and it would do it out of the blue , like if i stopped at a light it would run great good take off and everything , 7 lbs of boost , then at the next light it would want to stall at a stand still , and when i went to take off on green it would spit and sputter , maybe a backfire in there too untill it got to a high rpm and then it just smoothed out and boost kicked in and she took off. but the weird thing is it just does this at random .. how could it run great , and then all of a sudden not want to run at all ? thats my biggest concern with it at the moment .
