rb25det wont rev past 5k

Hello all.
I have a 1992 gtst with a rb25det swap and a power fc
The car will rev really good until 5k then kinda just stops and sounds like 2step splitters and doesn't really want to go past.

Changed spark plugs
Liquid taped the coils
Cleaned maf
Haven't had time to check for boost leaks but pulls great vac and hits full boost on the gauge when driving but doesn't feel like it goes anywhere feels slower than my focus st.
