I have been trying to troubleshoot my turbos because I cant get the primary to sproduce more than 8 lbs of boost so I have been troublshooting the best I can from this web site (By the way this is an excellent site!)

5) Check vacuum chamber's storage ability with engine off
Pull off vacuum hose at Charge Relief Actuator
Should hear air entering hose vacuum, re-attach hose
Start engine - briefly accelerate engine to WOT in neutral again
Turn engine off - KOKO 6 TIMES
Watch Charge Control Actuator work each time
Watch Turbo Control Actuator work each time, (need to crawl under the car to see this one)

I know my Charge Control Actuator works because of the test above but my Turbo Control Actuator does not move. I can get it to move using a vacume pump but not with the KOKO test. Any ideas on my next steps?
