Not at all. Barely drops when u put it in gear from park. Im talking driving at pretty much any speed in any gear,warm engine and go from 65psi to a quick steady drop when u go 1/3 or more throttle. I can put it in neutral and rev it as hi or as long as i want in any gear with no loss, butput in in gear and load the engine it drops. Not sure if it drops to zero but it drops steady and fast. I let off when i see it drop, but ive noticed it drop 20psi and come right back up when i let off throttle
