any one ever used a Apexi Boost Controller - Apexi AVC-R Ditigal Boost Controller http://www.modacar.com/products/Toyota/Supra/MODAAPE thats the web page. is that any good or should i not waste my money??? this is gonna sound dumb but what does the boost controller do i mean i roughly get it but i wanna know if it would ad any HP or anything like that

well a boost controller is wut it is...controls teh boost...theres a manual boost controller and electronic boost controller..manual...u press a button or flip a switch and it switches to a preset amount of boost...for example if youre running 8psi...u flip the switch now itll let you run 12psi...i think it regulates either the wastegate or the blowoff valve...someone check me on that....but electronic is the same...except you preset it at when u want to up the boost...like say u want to up it at 4000rpms...so once u hit 4000rpms it lets more boost in...u can do it at a certain speed too
