Might be better to ask my question also in the GReddy thread,
since i completed the build, the boost ( which was set to 10.5 psi according to the previously owner ) actes strange..
yesterday, while driving in very HOT weather ( 90+ fahrenheit ) it started to overboost suddenly.. which it usually doesnt do. ( yesterday was really hot, we normally barely ever going over 70+ fahrenheit ) So i started to think it might be the weather, but that should LOWER boost, not increase...
I usually have a solid 10.5 PSI of full boost but yesterday it went up anywhere to 12.5-14 PSI....
( i checked the vacuum line, it's good )
I DID ported the wastegate before the install, and im running a 3"berk ehaderback WITH HFC Cat.
One thing that i noticed during the instal, is that i needed alot of force to put the actuator arm on the wastegate flapper. I'm GUESSING it's NOT a 3.5 turn back from a zero point like mentioned in some GReddy wastegate actuator arm settings ( which should give 8psi if i'm correct )
Perhaps it's turned alot tighter than just 3.5 turns, making the turbo running higher boost and perhaps causing the little overboosting issue.
( the overboosting occurs already at 5000RPM! )
What do you guys think?
I also DO NOT have a boost controller, but i'm thinking of a profec B spec II...
I just need her to run a STEADY boost so i can have her tuned without overboosting issue's..
Hope some GReddy owners can help me out!

its gotta be the actuator rod if you adjusted it. Temperature plays a big role too. what is your air fuels? Usually the hotter it is the leaner your car runs.
