Dyno results....
250 HP, 245 ft lbs at the wheels (Mustang Dyno)
If you notice, the dyno starts ~4000 RPM. There's a violent stutter in the 3000-3500 RPM area as the turbo is spooling, so we had to go through the gears and start higher.
I think the peak torque would be higher if I could've done a full RPM pull.
It is nice to see that it pulls all the way to redline, no short shifting for me

I didn't have time to do it before the dyno...
I might get around to it today, but I've still got a lot of boxes to unpack (just moved)
If not today, then sometime this week.

nice....does the HP@50 mph make any difference or is it just a label?

I think it's just used as a calibration...
probably to account for dyno losses or something.
Mine was 3rd gear as well, the other cars did 4th, but the stutter I had was worse in 4th.
We have a timeslip database, we should start a dyno database....

Wait, if you dyno'd in 3rd, won't the numbers be off?
Last I checked, you should dyno in the gear closest to a 1:1 ratio, unless you can calibrate the dyno for gear discrepancies.
I THINK that if you dyno in a higher gear (or lower gear ratio), the numbers are inflated and if you dyno in a lower gear (or higher gear ratio), the numbers will read lower.
So, is your car faster or slower than that silly chart? ;-)

No, the dyno takes the gears into affect...
they start by taking a MPH reading in whatever gear the pull will be in at 3000 RPM.
The dyno actually reads MPH, then converts to RPM for the chart.
