my personal opinion, you cant go wrong, i had the mac cai and on hot days at the track you could feel a loss in throttle response, call it coincidense or what ever but i got in the 13's for the first time after i put on the veloity tube. the temps and humdity were about the same as before with the mac and i was runnin CONSTANT 14.1-14.2. first run with the velocity tube was 13.98 at 99.7, second run was 13.87 at 99.3.
my mods are as follows for those runs, the only diff was the cai . velocity tube, o/r h pipe, custom chip(which bumped up my timing to 15*) steeda tri-ax(now upr) flows 2 chamber(now spinntech) and YOKO tires. take it for what you will but i honestly believe this pipe helped ME.
later,
spidey
