The car still won't hold boost properly. I changed the seals properly so that's one issue eliminated to the fullest. Now the real issue.

I'm trying to figure out of its this greedy boost controller which I really despise. How can I test the waste gate actuator? to make sure its not the issue cause that's what I'm guessing is the issue.

I would slowly watch the boostguage when it creeps up to 13 to15 psi. When I gun it the boost quickly drops down to 10psi and the power loss is so bad I can feel it. I have Tbolt clamps all around so I'm trying to figure out what's the issue.

 

Try to disconnect the wg line and using the bicycle pump or similar start pumping the air thru wg nipple to see if rod is movig.that's what I did.hope it helps.

 

Do I leave the waste gate on the car still bolted up or do I just completely take it off and test it. I think its a stock 9 cause I don't see any makings on it or designs or nothing. But it does have an adjuster.

 

Have you tried doing a boost leak test yet? Also check for exhaust leaks.

 

Leave it on the car.that way you don't waist your time on removing/installing wg.

 

OK got it wastegates ok I think its boost or fuel cut . the car goes into limp-mode just letting boost work off the waste gate only xutiing me out. Brought it into the shop.

 

Ok,let us know what the deal is.
