Thread: HELP Not making full boost

put an actual boost gauge on it. it peaks 4 psi or so.

here's the weird thing, i tried disconnecting the vacuum line to the bbv, forcing the little arm on the supercharger all the way down. then, in park i revved it up to 5k or soo, and it was peaking out the digital boost gauge. i assume with the arm down it should be like running the blower with no boost bypass setup.

however, after taking it for a drive, setup without the upper vacuum line hooked up to the bbv, and it was making the exact same boost.

so i guess, it can't be any part of the bbv. how about the boost solenoid ( right next to it) it could be when i spray it, it was getting into the hole on the electric solenoid. also, should there be an open nipple on it? (no hose hooked up)?

if not, i don't know whats going on..

anybody have any ideas? or am i just crazy
