I just installed my turboxs stealthback, thanks to JSCspeed for the great deal. It adds a decent amount of power and gives the exhaust a more aggressive note. I have noticed sometimes when i give it a quick burst to full throttle then stop soon after it will sometimes smoke quite a bit. This leads me to believe the PCV is throwing oil into the intake. It might also be because I have slightly too much oil in my engine. I have 6 quarts vs 5.5. Other than that it never smokes. What does everyone think?
