this is the SBC spec-id spec s boost controller. when i got my car this was in it but with no boost controller so i bought a MAC 3 port from AEM and used that for a while. here are all the specs on the controller, its a pretty nice setup and the mac should control boost better then the blitz unit that came with the kit. it has a full boost plot and peak boost setting so you dont have to watch it as you drive.
