Truck is sluggish from dead stop/low rpms
if i stomp on it from a dead stop or lower rpms (low turbo spool) it seems like it shifts to soon or something. if i wot from like 2k rpms it takes off and pulls me in my seat. it also sucks for towing its hard to pull at lower rpms but once it gets going its fine. im also straight piped. is it my ebps? also my exhaust is ghetto from previous owner...he left in the original 2.5in tube from turbo to like end of cab then in turns into a 3in then turns into 4in (i did the 4in and ran it out the side) would that effect it?
