ok, i have a 1992 745 tic, my old 13c had gone up so i decided to do a 15g swap. got a good one with little play, rebuilt it anyway... reclocked it, installed it... test drove and .... 5psi max! any ideas on what i f'ed up? my old turbo (13c) would do 12psi with the manual boost controller.. this new 15g is only putting out 5psi and takes a while to get there.
 
awesome, i was hoping it was something simple. i tried pulling off the valve and shimming the spring as well as disconnecting the wastegate, but still only 3-5psi.. thanks for the input... now to find one..
 
Ok, I'm going to silicone up the two small holes in the cbv for testing. I don't know if my preload is correct, I'll check that too. Thanks for the info
