Dave thats a really smart way to set your mbc, i'm definately going to give that a try come spring.

I don't know how your connections are coming apart if you have decent clamps on there. Do the hair spray and clamp the shit out of them and also make sure that the pipes are lined up directly inside the coupler. That could be your problem.

works wonders, but you have to have the +/- thing turned up a little because the gauge in your car is reading manifold pressure not the pressure from the turbo, so fine tuning is still needed... i have found that when setting my MBC using this method to 20psi, when i put it all back together and did a 3ed gear pull, i was actually closer to 25psi... so i had to turn the hand adjust down 3-4 turns to get it right at 20psi... entire process took less then 20 mins... went from 15psi, to 20psi... and only had to do 3 pulls before i was RIGHT on the money!

keep in mind, i did this with a bike tire hand pump and just "pressed" the vac line into the connector on the pump, and didnt "latch" it, it worked more or less almost perfectly! i also had to push the pump very slowly because quick pressure changes will void the process since the pump will move more air then the MBC can move at a given time... when the boost controller opens, it will make an almost "buzzing" sound... just FYI... mine was really quiet and i had to actually put my finger just after the MBC's outlet to feel when the valve was opening...
