Vac and Press

Ok, I just put in the aftermarket boost Gauge, in the brake booster line. So i get in my ty and start do drive it down the road. and i was in drive and put the gas to the floor. and i only have 9, 10 psi so i thought i had a leak.
So i pull over and my vac is like 25. what can i check to get my boost back up th 14,15 psi. All the Vac lins on the turbo have been replaced.

check to see that the vac line routing through the wastegate solenoid. Check to make sure the solenoid is plugged in.

I had the same symptons when I put a boost guage in, it turns out I was only 9-10psi and then slow buil dupto 15-16psi. Look at a scan tool and it will tell you haw much boost your getting.

everything looked good hose wise and the selinoid is pluged in. I only build 9 PSI no more, thats from a dead stop First gear 9 psi, second 9psi, drive 9 psi thats never getting off the gas.
Can i just put a manual boost controler in place of the selinoid?

thanks
Later, keith

It only makes 8psi with the solenoid unplugged, so it seems to be that the boost solenoid is dead
