afr cant be right?

[schumy]

i have a 95 gsx and im running 750cc injectors and its a fresh rebuild i havent been able to drive it cause i have no idea what the afr is i have a wideband gauge and im tuning it with a apexi safc today i just replaced the maf sensor and on the safc no matter if i add air or take it away the voltage on the safc stays the same and the wideband freezes on 19.5 now should i be running rich because of the injectors?? and i just took out the ecu and there is a jet performance chip in it could that be a reason the afrs wont change? thanksss

750cc injectors with a safc is not a good idea it all depend on the turbo you are running and what program is the chip set up for than you take it from there

Put the stock injectors back in and zero out the safc until you get a wideband. You are going to blow up your fresh engine.
