Hey guys i got an 00 si with basic boltons, i/h/e was wondering if vafc and adj cam gears are worth it, ive read mixed opinions, some people say the si runs very rich(mine does) and i could squeeze some horsey's with the two together after gettn the car dyno tuned... yay or nah?

 

with just i/h/e, no its not worth it for the few non-noticeable horses.

run rich? fpr will do the job.
