Off Idle hesitation

Off Idle hesitation
I actually have two problems, related or not I'll post in different threads. This one is an off idle miss or hesitation. Happens just off idle when driving only . Not noticable when just trying to throttle up when parked. It happens from 2-4 pounds boost when easing it up to speed in any gear and only seams to be felt by the driver (no comments from passengers). I have a constant 18-20 psi lift pressure from the Airdog 150 on stock powererd engine. Lift pres. is tapped at the fuel inlet to the VP and is sent to a sending unit that converts it to an electrical signal sent to the electric Westac gauge on the A pillar. I have calibrated or better said (compared) the gauge with a direct pressure reading gauge tapped parellel to the sending unit take off. This miss was also noticed prior to my installation of the new fuel delivery system. After the initial hesitation at off idle the normal driving range and WOT seam to be normal. no miss no hesitation and plenty of pulling power. I have no fear of the engine shutting down at all. Idle is normal about 850-860 RPM and no problem getting to 3K RPM in a heart beat or two with the NP 6 speed tranny. I'll do my other post right after this...something to do with cruise control and pac brake. Thanks for your help. Let me know if I didn't give enough info. Been on happy hour for an hour or so. cheers
