I was just wondering how this works since the IM under a turbo is now under positive pressure, doesn't that screw up things like your MAP sensor and even your brake booster?
 
brake booster has a one way valve. while brake boosting its real hard to press the brakes in b/c of no vac. you tune your car with a program that lets your map read boost up to 11.xx psi.
 
Yes, it is very difficult to brake while at WOT lolz.

erebunicrx is right, and usually the PCV is relocated to the pre-turbo intake, which is a vacuum source even while boosting.
 
right but you dont want to suck that shit back in... slash cut into the exhaust would be the best way.
