I've been teaching my self how to overhaul turbos and properly adjust both the waste gate and the ALDA ~ WOW what a difference ~ more power and much smoother plus increased fuel economy and the cloud of smoke is reduced and perhaps gone ~ I can't see it in the rear view mirror anymore when leaving a full stop .
