looks like we are about on par with each other, yours must have been slightly more run in than ours, I'd bet we put down a bit more if we went back there with the 5000 miles that are on her now. . .
most dynos should be corrected for ambient temp. etc. I know the one we ran on was connected to a weather station to automatically get its correction factors for baro pressure, temperature, etc.
