I have the same issue. Never tried the map 4. But switching from regular automatic mode to sport shift mode, it never smokes accept if I got into moderate boost and come to a stop really quick. Even then its negligible.

I've always been baffled as to why it wont smoke 98% of the time in sport mode. Assuming has something to do with the heavy engine braking that is introduced in sport mode.

I've converted to external pcv system from RBTURBO.COM and have the bms high side catch can as well. Valve cover and gasket had been replaced right before I purchased the car. Rebuilt head as well
