i'm curious to see if anyone's done this. i've seen a lot of dyno sheets where the motor will make peak power at about 6k rpm, then dip and go back up to that pont, then again...

i'm wondering if the computer is closing the throttle partially for whatever reason.

anyone got any datalogs, or any info on this?

 

Happened to me. I think the throttle is closing, but don't know why... Here is my dyno, look at the black line. At that point it goes rich as a pig.
