the car wont hold boost! i step on it, it hits 10 psi, then it bleeds back down to 5 psi. if i keep it floored it will very slowly build back up to 10 psi but by then im going 120+mph. sounds like a wga to me but i still read 27 in/hg, yes my car has super vacuum. wouldnt a hole in the wga cause me to have a vac leak? help is appreciated, thanks.

What happens if you disconnect the BC?

Vac leaks are less evident than boost leaks sometimes. A pinhole in a vac line would expand under boost. You can pick up a brake bleeder/vac gun from auto parts for $20. Hook it up to the wastegate actuator with the car off should hold a vac. Then test your vac lines. Couplers also! Just read you have stock piping which can also be part of it.

i found then problem. didnt realize the adjustment knob on the bc backed itself all the way out. it was sitting on top o the power steering pump lol thank god it didnt get caught in the belt. i put it back in n it holds boost fine. i also found a whole roll o 3m stick tape lol god im an ass!
