well i know for sure i have no boost leaks anywhere. but the prob is . if i go WOT starting in 1st i will boost to my full 8 psi like i have the boost control set for, but then when i hit 2nd the highest boost will go is 5-6 psi max.. and 3rd i havent tried but 2nd gear i am supposed to be getting 8 psi but it stays around 5 at WOT.. but the dumb thing is if i am in 2nd and i give it like 3/4 throttle it will easily boost to 8 and stay there.. so what could this be? i have a home made boost control and it works fine so i doubt its that but i dunno.. its only aat WOT that is stays at 5 and only in 2nd gear.

i just re did the seals on my MBC and now it seems ok.? i dunno if that was the real prob though but its working at full 8psi again now..

It must have been the problem then... It's harder for your turbo to spool when your rpms rise slower (aka later gear).
