how to set the wastegate rod?
the rod going from the actuator to the wastgate held on with a clip. how do you go about setting this. it is threaded and you can shorten/lengthen it. i noticed the resistance is different on the one i am running. it is considerably less effort to pull it open by hand where as the one on another motor i have is tight and requires more effort to manually open it by hand pulling both by the center of the rod. any help on this?

thought the boost were controlled by the vaccum on the actuator? i just want to make sure my wastegate is not staying open some. i don't start getting boost till 3000rpms and hit full boost at 5000rpm which right now is only at 14 psi. i have a manual boost valve installed where you adjust boost by tightening/loosening the ball spring pressure on the manual valve. so that 's how i adjust boost. what is the adjustment in the rod for? need a expert on this area here or anyone who has played around with adjusting theirs

You want the rod to site about 1/8th to a 1/4" BEHIND the wastegate pin. Yo want to pull the wastegate rod onto the pin. Also full boost by 5000RPM is not right, yo should get full around 3000RPM

It's possible that because it has less resistance than the other you are looking at that is is partially opening while you are building boost, and that is why your boost is coming on so late. Would it be possible to swap the other one over to test it out? If it solves the problem you know you need another.

dunno about swapping them as i have a bigger turbo on the car now. it's not much bigger it is a .63 hot .70 compressor. dunno if that would change where my boost would be. does the rod control when boost come in during the rpm range? lets try this does anyone have any measurements of their car's actuator rod? would like to get a measurement from the rod center hole of where clip is to say butting the actuator ??? or where ever is a good point to pull from. i will measure mine this evening and compare the stock vs whats on it now.

Yea your not running a tiny IHI turbo, which was designed to have minimum spool up time. the bigger you go without help will take more time for the turbo to spool. Unless you spray or run a two step.
