SO here's the deal $1500 later and the car is still running like shit...but.....if i unhook the boost bypass valve and cap the vac lines it runs about 9psi.....if i run htrough the bypass.....i only see 4psi

Also, according to the scanner, at idle it only reads -8 to -8.5psi ...... we took care of all of the Vac leaks, and even put in all new Injectors......

what the hell is going on.
