first tune stock turbo
Your AFR's are jumping all over the place just smooth it out. Plus if that AFR is right your running 12.0 at peak TQ which in my opinion is a little lean, its fine under spool up though running that AFR. Try 11.3-11.5 after spool up through out the power band see if that helps. Otherwise Ide say decent power on a Nine with just 25 psi. (I may be wrong however I heard Evo 9's can run a leaner afr then 8's) But I figured ide throw in my two cents.
