there are 2 small connectors under the TB one is pre throttle and no good,
other is post throttle and will give best vac reading,
delete the OE boost solenoid completely
just run line from turbo compressor/boost source signal to GFB boost valve thingy
> wastegate actuator, don't run any lines to the OE solenoid
BEFORE TESTING WIND THE VALVE BACK OFF,as it may spike like crazy/over boost with direct line
