no never figured it out. p.s. sorry to respond as late and thanks for trying to help. the thing is, i don,t have any vacuum leak, when i pull out the hose even when truck is off for a while it still get lets off vacuum, so its holding vacuum good. i would think if the booster is bad than it would be really hard or stiff. i did turn up the idol a few hundred rpm,s to what it should be, and it helped a very small bit, i think, but still not right. it was great before the v8 swap and now crap. it is worse at idol than driving down the road i've noticed.
