Did u run NEW hosing from wastgate to the Turbotech boost cont? or did u use the old red and yellow hose.
To hook up a bleed boost cont u need to run hoses from the wastgate and then use the red hose , plug up the rest. Then unplug solenoid.
When i used the 2 hose connected to the solenoid, it gave 8 psi no matter what i did, i got better response with just removing the restrictor in the yellow hose.
Only on a GTR!!
