Have you ever told us EXACTLY how you have the manual boost controller hooked in?

A softer or stiffer spring will not improve the "low power" that you say you are experiencing. All a softer spring (9psi, stock) will fix is driveability issues if you are having them. Like surging, stuttering, etc.

Well my dad came over and he found a leak , a HUGE leak last night when i tested it it didnt seem to have i leak however i was wrong, there is a very loud hissing sound coming from the throttle body . I cant even get the car to hold 10 psi but when i was driving it it was hitting 20 psi , imagine how hard my turbo was working to maintain 20psi man im an idiot . Ok so now i know that i have this huge boost leak i assume thats my issue right there . The exact location of the leak is on the spring where the thottle cable connects , it also sound like its leaking from the backside of the throttle body. How do i fix it ? what do i need ? thanks for all your help fellas

for sure... this would also explain why the throttle has been sticking when you rev it up in neutral. your shaft seals are destroyed on both sides of the throttle body.
