boost gone at 4500rpm
I installed new turbo's, down pipe high pref. cat etc. When I took it for a ride I was ready to rock. One small problem at 4500 rpm's the boost went from 8-10 lbs to 0 lbs. In any gear over 4500 boost is 0. At 0 boost my riding lawn mower can pass it. Any sugestions would make my day.
Houston we have a problem !!!!!!!!!!!!!

Welcome to hell. I suggest searching this forum for anything related to your problem. I bet you there are more posts on this subject than there are Mc Donalds in this world.
What makes your problem such a problem is that you replaced your turbos. There is a big chance that you didn't route the vacuum lines correctly, or that you attributed your earlier problem to bad turbos without addressing the system as a whole.
If you replaced your turbos because you thought they were a problem, take a look at your turbo control solenoid on the vacuum side. It is prone to fail before most other solenoids.
Without getting into all the details again and again, please do your self a favor and search using most of the words you used in the subject line.

LAracer I took your advice and checked into the link you provided. After reading this info I feal I can dial things in, I had already started to trouble some of the stuff and have come to the conclusion the the vaccum hoses are left over from the stone age. Hard as a rock and can be used as nails for home remodeling. It's refreshing to comunicate with someone who cares and dosen't ware their ego as a bagde.
Thanks Dude You Rock !!!!!!!!
