No Boost!!!???

I dont even have to rev the engine. But yes I can hear it spinning. Before I changed the boot on the turbo and the lines. It would lift from -4 vacuum and 0 out due to a cracked boot and slightly pinched off line. Now nothing I spent more time putting it together and double checking what I was doing. Still nothing.

so the gauge is showing a vacuum or just 0psi?

At idle it is -4 psi and running up to around 3000-4000 rpm it 0's out no boost. From -4 vcm to 0 psi. Any ideas?

try disconnecting the cat and cat back. might be exhaust system clogged or something. you sure the gaskets are air tight?

I actually have no exhaust on the car. All that remains is the downpipe back to right under the passenger seat. The gaskets are all new and torqued to spec too. I found a pretty major leak on the intake fixed it now I can hear the turbo spin while under load runs better too. Still the same reading and no Blow Off.
