I think you need to tune it personally (if there are no boost leaks)..

My stock CT hit FC at 14psi. This upgraded turbo hits FC at 11-12... But I don't know what is the best way so I am staying out of it.

Well I understand that if you get a bigger wheel, you are going to have a quicker FCO (ex.: Stock CT: Fuel cut at 15psi --Upgraded CT: Fuel cut at 12psi)

However, 2 Days ago, my FCO was at 10psi...then yesterday it was 9...and today...I cannot get past 8!

Fuel cut is not my area, lol...

Here are some good threads on fuel cut that may explain it some.
