you're using a VAFC which means the ECU is still running closed loop.

which also mean that the narrowband o2 is still correcting AFR's

so the vafc only programs it when im boosting.. if i got a wideband and 450s with vafc would it be pretty easy to tune or not?

no

just get a chipped ecu and then worry about tuning. there really is no way to adjust the vafc for only when your in boost.
