I installed sda cams on my 93 sc2 and now my vaccum is down around 12 at idle. I would like to bring this up because it makes the car idle down way too low and changing the idle obviously has no effect. Does anyone know how I can raise the vaccum? I heard about a vaccum cannister but i dont know how it works or where to get one. Any help would be greatly appreciated.

 

i dont know how you can increase it, but i have the same issue with a V8 car. I put a very steep cmashaft in it, and i lost my vacuum.
