Stumbles at high rpm then loops

[driftn1g]

well i seemed to get it better.. also ran some seafoam in it

i looked at my fuel trims Low is 129%, mid is 99% and high is 85%.. but i also dont have an adjustable FPR so i was told leave them alone??

cant remember how to adjust them, i had a write-up somewhere but lost it.. but i did get my idle to where i wanted it (750rpm)..

right now it seems like it will stop pushing at like 5k-6k, but is boosting..? rich??
