redline 4750rpm, speed limiter hit at 112 miles per hour so we could not pull to redline. i didn't want a tune or remove speed limiter yet.

The loop is you hitting your limiter, the RPMs go down, there for dropping the graph backwards, making your loop.

Yep. Makes sense to me.

if it was my limiter wouldn't there be more loops?
I mean, there is one loop at mid-rpm, and then we continue to pull past the loop for a bit. If it was a rev-limiter the dyno graph wouldn't read past the rpm limit, right?

He never hit at redline.
But why is your redline so low, I didn't think that the v6's revved that low.
Also, what gear was this done in?

I think it is an issue with the dyno, if you notice it shows up on the HP and the TQ at the exact same time on each run. Where it shows up on each run is not related to a RPM, HP, or TQ number, it is related to the time after the start of run. Look where the curve actually starts and measure across, for both runs the time is identical from the start. I would say it has something to do with some timing event triggered by the start of the dyno run.
