so is there a difference between waste gate chatter and turbo chatter. i was always lead to beleive the chatter was from the turbo stalling but several people have said it from the wastegate fluttering.
also i could get very light chatter from the ke jetronic systems. i found if u easy of the throttle but not full close it the flap stays open enough to let some air out. either that or my metering unit is fudge like u said
