So I thought my ecu was only tuned for the gt2871r and the 740cc injectors so I was using safc to tune the z32 maf I pulled the safc off today because I was having problems under boost and was gonna rewire it tried running without it it runs great???? Anyone know why and is it safe to run without the safc

wrong section but as to your problem no dont run it without the tune if you end up running lean youll blow your motor.

Need more information.

What tune do you have, what was it tuned for?

Why did you drop a Z32 maf into your setup?

What were the in/out settings of the SAFC?

Ecu was tuned for the gt2871r and the 740cc injectors.
Was using safc for z32 maf 2in 5out

Barely legible but I think it says z32 so I'm guessing the ecu is tuned for it so I don't even need the safc????

I use my SAFC for correction on my enthalpy ecu. Can help with throttle response.
