Not good man! My mate recently just had his fg done with GTX, factory motor, factory fuel rail, no surge, built zf with 3200 stall and made 400rwkw on 19psi on 98 fuel with 11.1 afr's so still quite rich (waiting for gearbo tune). Another mate with a BA and built btr with 3200 stally made 340rwkw with gt3540 on 98. I didn't read how big your stally is but can't be robbing too much. At that psi on e85 guys with FG's are making 500rwkw through built zf's with stall's Definitely sounds like the tune needs to be fixed anyway, maybe tell spiro you want to diagnose the issue at your cost
