hi to all again, i made a boost leak tester and ran it on the car...the pcv tubing across intercooler had air rushing out of it (along the right hand side that goes down near the fuel pump...i have fixed that up now

surely that cant cause a vacuum issue? thinking about it, it probably can... :P any one else confirm it can?
