OK the vehicle is a 2000 chevy truck with the 5.3, has the Tr224 112 lsa cam..Has 2001 custom operation system, also tuned speed density with out a maf.when i go to rev off idle its kinda sluggish is there any way I can get a snappy throttle response through the tunning?? anything in the throttle cracker or follower would help this?or is the intake holding this back?
