i was thinking of buying one of these vfac's, mainly to lower vtec(5200rpm). but is it worth 250-300 bucks? while your reading, should i even lower vtec? good?bad? it just think having access to the high cams earlier would help acceleration a bit. i know that once a go to a sc setup i will have to raise my vtec point back up, but a sc is years or so away. any help is apprecaited.

vafc fattens up your midend and topend depending on mods and how good your tuner is. tuning and dyno time cost $. lowering vtec too much can actually make the car run like crap.

so i should just leave it be then?

yes

before and after tuning. vtec kicks in at 5700. notice fatter midend and how power doesn't drop after 8300. a/f ratio was flat throughout powerband at around 13 i think.

too bad it drives like shit at 1/2 throttle from 5700 - 6500 rpm ....... but if you like that sort of thing .......
