To the pressure actuated wastegate. This is on the 1990 300d with 190,000 on the clock. Lucky for me, ATP is only 15mins from my house. A few things i have noticed. Im only getting 11lbs of boost, 12 max. When i hooked up the new actuator, the wastegate was completely closed. I tapped the intake at the test port for the wastegate and the boost gauge. On the highway when i floor it, it doesnt have that much get up. Almost like it bogs down. If i let off the accel a bit, it starts to take off. So its kinda of like it accels when i take my foot off the pedal. I have the egr and flapper disconnneted along with the vac feed off the pump that heads over to that rats nest.

Some background: new injector pump, Clean bango to alda line, little play in the turbo, clean fuel/air filters. Im currently running about b75 in the tank

Anyone have an idea of why im not getting the 14lbs boost like others have mentioned? also, any ideas about the accel issue. The car feels better to drive, but i think it still has more to give....
