    Data logging question.....

    I did some data logging tonight and noticed that I am hitting 100.0 load% by 6200 rpm but my MAF readings continue to climb upward to my 7200 rpm redline. At 7100 rpm I am getting 432 gms/sec.

    How is this affecting my fuel and ignition? Should I try to adjust the orientation of the MAF so that 100% happens closer to redline?

    Any ideas?

    Are you pegging the MAF?

    432 G/S seems low. I was seeing considerably more a smaller boosted engine. It was a few years ago but I want to say it was around 600. I could be mistaken but that is what I remember.
