+1 on that. You max the MAF and now are resorting to fudging up the tune to try attempting to get the fueling right.

I noticed when my maf maxes lbs/min the frequency still rises.That can't be used for tuning in any way can it?

You can scale the MAF by half and get double the flow out of it, up to 1024g/sec instead of the default 512g/sec. It is an involved process, and dont ask me how because I dont know

you might could get 600rwhp out of it but its not the power but how much airflow it can detect, it can only handle so much

I ran a MAF with my Procharger at 10 lbs but Rick @ Synergy had me switch to a 2-Bar and SD when I put the turbos on. The SD tune works great year round here in Nor Cal.

I look at the MAF like a failsafe for blow through forced induction. Once you obtain a reasonable amount of boost it conveniently separates to prevent engine damage.
