Follow up. I adjusted the fuel screw again and eliminated the concern I had when the throtttle was snapped idle to high rpm the engine rpm hung before idling back down. Idle speed adjusted after.
Re boost drop off. I removed the boost diaphram and checked the boost pin rod in the pump for freedom which connects to the boost pin. It was ok. I turned the star wheel 1/4 turn in. I set the boost pin to max travel removing the plastic spacer. Refit the boost pin with the ramp on the most agressive side contacting the pin.
Road tested and the boost now holds when the trans shifts and is much more responsive once the turbo kickes in.. At 55 steady Im running 7lbs boost. The truck is heavy so acceleration in top gear converter locked is slow
