SLP 85MM MAFS question
I have heard mixed reports of tuning issues and what not. Also, is my stock MAFS able to monitor/handle my engine output? I easily have over 600HP at the crank.

Should I get the SLP MAF or not?
MAF, and pick up a pigtail or adaptor harness. At least then
you will know what the calibration should be.
Look at your MAF output frequency or airflow reading. If
you are seeing more than 450g/sec for airflow then you
want to stay away from the 85mm MAFs, they all top out
sooner than the stock 75mm (459g/sec vs 511g/sec, at
the 12kHz PCM limit).
