The fuel pressure drops about 8 psi when suddenly opening the throttle. It then climbs back to 55 psi under part throttle and remains at approx' 55 psi on road test.

I did not check the vacuum change to pressure you would normally expect as there is no hesitation . I will do that tomorrow.

I am sending all the injectors for sonic cleaning and checking to eliminate them as a contributing problem.
