I have 2 maf sensors. Both Granatelli. One is the normal one they sell, and the other one is a CAI tuned MAF.
I'm ridding on the first MAF cause that's what is tuned for, but I tried the other one, just to feel the idle and the low RPM range erratic until 2500-3000rpm. After that felt the push. On sensation base, It felt more recovery in the 4900-6700 range. Could not log some. Try that this weekend.
Does anybody knows the difference, and wich one will work best?

Everything I have read says they are both junk. Cause more problems than gains. Go back to a stock one.
Gone, but not forgotten!
Either way, you would need to calibrate the sensor to your MAF table. I think one is designed to trick the pcm in thinking there is a different airflow amount than normal. Custom tunes are there to correct that problem.
