Hydro-boost is what chevy has called it for many years. It gets it's vaccum from the p.s. pump to run the brakes. Is there now vacuum at the wastegate after changing the vac pump?
I haven't talked to him since this morning when he told me about the balancer. Hopefully I'll be able to let you know after work tomorrow. He said the vac gauge didn't read when hooked straight to the pump today. I wonder if the solenoid wasn't bad in the first place? Just the pump? He doesn't have a boost gauge so it will just have to be seat of the pants to tell if it totally fixes it.
