HELP!!could my vacuum hoses colapse under boost?
i just installed my safc, and now i get a major hesitation that works through it self when ever im in low gear at around 3k just at around 1 pound of boost. the safc isnt really tuned well yet.
but could the vacuum lines be collapsing on them selves? there brand new.
and is it possible there could be a ground problem?

Your question doesnt make sense since boost is positive pressure and vacuum is sucking. If anything check to make sure all the settings on the safc are correct (correct flapper, correct in/outs/ 4cylinder in diagonal up right position).

im just really frusterated cuz it wasnt having this hesitation before the hook up.
however a while back i had a hesitation problem, that was due to the tps.
Q-does the tps do anything when the turbo starts to spool?(around 1/3-1/2 trottle)

There are 2 settings. 1 is a dial (I think 5 is FC) and the other is several switches for different ECUs.
TPS= throttle position sensor
It has nothing to do with boost. It just makes random hesitations if it's not adjusted.
