I just upgraded to a GTI-R T28 and when I put on my tubular manifold I had to delete the stock catch can and currently have crank case ventilation connected through the T on the valve cover and into the turbo inlet. My HKS adjustable actuator is set to 9 psi.

During a pull the car boosts really hard and doesn't smoke while i've got the pedal mashed and doesn't smoke when i let off. as soon as i hit the throttle again however, a burst of blue smoke comes out. So basically I am wondering if this is only happening because I don't have a catch can, and if its normal to lose some oil during normal operation. The car burned absolutely no oil on my stock T25, but then again I was under stock boost and had the stock catch can set up.
