Well whatever the case may be, my latest virtual dyno pulls for my rev6 are pretty impressive. The first one (red one) was done is strange conditions so I'm taking it with a grain of salt. The second one, obviously impossible since I have a stock turbo (and virtual dyno isn't always 100% accurate). Nonetheless, the numbers are pretty much where I want them.

I'll see what Mitch says but I should be good. Also, whatever he did adjust for the SST does make a difference, whether or not he was able to go as deep as Open Source. The gears engage really quickly and there's less "stuttering" around.

The second image is a graph between time and RPM. Seems a lot more linear than before hopefully meaning the slippage is gone, or diminished.

The SST graph is from the second run (blue lines).

another thing to keep in mind is if you're doing this on the street, rises and falls in the road can cause variations in your graphs... when the car goes "light" because of a dip, it's able to change RPM slightly faster than normal... it will also prevent you from achieving a perfectly linear RPM vs Time graph...

There's a stretch of road that I use near where I live that has a slight dip at the end of a 4th gear pull and it causes my graphs to have a HP/Torque spike at the end of the plot every single time. I usually "mask" it by increasing the "smoothing" that VirtualDyno uses to the 6 - 9 range.

Well as you can see from my RPM graph, there's very little movement. I did it on a straight, brand new paved road so there is very little flucuation.

I obviously know Virtual Dyno isn't accurate either.

Regardless, still a pretty solid result.
