the problem is the boost controller is set at 12 psi (aem tru boost controller). im suing an sts turbo on a 6.0 with a t56. the boost fluctuates and doesnt stay on 12 but reaches it in some runs and other runs gets 7-8 only in 3+ gear. 1st and 2nd gets to 5-6 psi. i dont know if the problem is from the controller or the wastegate.

i have a aem tru booost controller on my 92 typhoon. i have it set at 16 psi. it will go to 16 drop to 12. go back to 13 back to 8..... mine fluctuates very bad too. and the worst part is i can drastically feel when it falls off of boost..

so would you think the problem is the controller itself? the arent any leaks in the turbo piping.

i played around with the settings a lot, i think i had it set at 2.00 or something like that. i thought the controller only raises and lowers boost.

This problem sounds like a typical sts car. You might want to check the system for leaks and make sure the exhaust is not worse then factory and wrapped to retain the heat and help spool the turbo.
