MAF reads 65lb min maxed out @ 4k rpm, but MAF HZ only up to 10k??

[AidanN20]

I am trying to tune a procharged 5.3l 2011 truck.

Its a bone stock truck with just a procharger p1sc kit.

When I log the dyno run, the scanner shows the MAF lb/min gets to 65 lbmin and maxs out (stays 65lb through rest of run) by 4000 rpm.

I am logging the MAF HZ and it is only 9000 at that point and climbs to about 10000 by 5000.

I am having problems with truck going lean with plenty of injector left etc and i dont know why it would show maxed out lb/min but still room in the hz to climb.

When I add to the maf table it doesnt richen up.

The limits are independent. You can't exceed either the flow or frequency limit. If you are maxing out flow with room in the Hz then you can artificially lower your IFR table and then artificially lower the MAF table(s) and any other airflow/airmass related table to stay under the 512g/sec / 65 #/min flow limit.
