Watch the blower case temperature when dyno testing @ WOT under boost.
If it gets hot after a few pulls , stop and let it cool down. thats what the water/methanol injection is for.
dead cold blower case ='s backfires and fuel wash and fouled plugs poor idle . too hot blower case ='s risk of detonation under boost.

02 sensors can give false readings ( exhaust leaks, blower pass thru ( too much cam overlap overscaveging) ignition misfire)

ALL 8 plugs appearance and exhaust temps and trumps AFR/02sensor readings

Test with power valves plugged (remove and plug) and big primary jetting +6 to +10 jets sized up. untill you can get the carbs boost referenced. Thats the best you can do with those 1850carbs.
