Post up a graph of the torque and 5 smoothing. Can you send me the runfiles, please?

I think I see how this was done now, and I think I don't like it either, but I have a few questions for the man above to confirm that.

I'm not familiar with this dyno program but why does my tq jump to 230 when I change it to speed or time vs engine speed. Are these numbers correct and just not recorded because it's possibly over 6500 rpm. Take a look cuz I'm real confused plus I like these numbers much more

They are called tourqe spikes, and there might be other causes as well but the two that I am aware of are 1: (yours) Downshifting during the run. and 2: bad vibrations or any issue with the magnetic pick-up for the rpm signal.

And since you like those numbers better it really does hurt me to say this, but even on the other graphs the max tq #'s are spikes as well, for example run 005 says 201 but it's closer to 185.

I was at the dyno for a few hours yesterday and your runfiles got opened up and discussed, the tourqe spikes and lack of consistency were noted by all.

As to why the tq spikes go even higher when displayed against time, definitly don't quote me on this because I have no clue wtf I'm talking about and would like confirmation. But my geuss is that, when displayed over time it shows every gear that the runs were done in, where as when displayed over a certain rpm range it selects one particular gear.

Nice numbers. Just out of curiosity why did you start the runs at such a high rpm?

Does it seem normal that max tq would be at such a high speed when I pull the run with rpm on the right side it shows peak tq at about 4800rpm which seem right but not at 120 mph
