Has anyone else had problems with their turbo boosting about 1.5 lbs at idle? Mine was to the point where I could hardly get going from a stop light from so much air being shoved in the cylinders. After talking to Keith at GDE I decided to to lengthen the pull rod on the turbo vacuum diaphram. I figure I lengthed the rod three turns before I achieved no boost at idle. Now it runs great and gets much better mileage. I believe the spring in the vacuum diaphram becomes weak after so many heat cycles and doesn't resist being pulled open. Hope this helps some folks out of they are having trouble....
