Need help like, when i get the turbo and stuff and get it tuned, would i still need a VAFC controller to lower when my vtec kicks in, or should the EMS take care of that since it is all being tuned? Just Fill me in because i dont want to waste money on a VAFC if i do not need it. Thx

 

what ems are you going with aem? if so you don't need it aem controlls vtec

 

ditch it, ems already has a vtech setting
