Question Boost problems please help

I just installed a new head with new Titan 2mm gasket.
I figured i would upgrade the exhaust manifold and turbo.
I got a Super T4 and a turbo XS exhaust for my 90 Supra 7MGTE
I installed the head and the manifold, added a Tial 50 mm wastegate
3" v-Band and exhaust pipe. Wastegat vents to Atmosphere.
Also put on a BOV.
The car starts and runs great at idle. I cant hear the turbo,when I stomp on it and release, i should hear the BOV go whooosh but nothing.
The turbo doesnt seem to spool all thou it is turning.
I have an aftermarket boost guage and shows me -10 when I accelerate it goes to 0 but no boost !
I have no leaks but no boost anyone have a clue?
