heres the problem, i had recently took off the manifold to get welded because it cracked
i then installed it back on with the old gaskets and now its not boosting... that pull at boost..
i get a boost reading...
my question is that.. can a exhaust leak from a gasket cause that??... wastegate??.. manifold to turbine??... can a dump pipe gasket cause that???
and where can i find cheap gaskets for t3t4/t04e..
anything will help if it leads to solve the problem

 

Yeah It sounds like you have a leak somewhere. Have you pressure tested the system?
