turn up the boost controller. or without the pipe hooked up to the intercooler/carb, take the signal off of the wastegate and rev it hard with your hand over the opening. its should blow your hand off the opening.
I have the boost controller disconnected right now, just one hose from turbo to wastegate. I'll disconnect it, and try that. Would I be able to do it on my own using the throttle lever with no load on the motor? I lost my help, he had to go do errands.
