i watched a few videos and i can't say by watching them if thats what I'm experiencing, but so far it sounds like a pretty good educated guess. I've been being told its got something to do with the vacuum or something on the s/c and built up exhaust not having anywhere to go except out the exhaust, unlike a turbo which has its own 'point of release'
that even make sense?
And Procomp uses lift blocks in a lot of their kits. Blocks make it worse.
