I have a 1g swap in a 2g when I used a stock maf it was running pretty good but dont have it anymore went to 3inch gm maf and installed a safc II as soon as I installed the maf the blow off valve is much louder also in order to get it to not have fuel cut I have to go -50 or so in the safc the wideband is being completely crazy so I dont know afr but ordered a new one. I am wondering whats the deal why is this so difficult what am I missing. I tried running low boost and more boost either way it will has issues with acting like it has too much fuel. I am thinking its just a problem with the gm maf with safc cause my v3 works like a dream with the gm maf but not this one. Please any assiatance would be helpful
