LOL! Nope, I'm not gonna do that. I have to get some numbers and some safeguarding for track use before the next event.
I was scheduled for 2PM then changed to 3PM. They had a stock car on the dyno and I was in line after them. I waited and waited and they ended up taking all the time. :( I spoke with the owner and I am scheduled for Friday morning.

I hit 315WHP and 251TQ at around 12PSI (179kPa) on a Mustang dyno.
We then de-tuned to approx 262WHP for my class.
I also got a four wheel alignment while I was there.
Videos coming soon.

power/torque is not no same scale but just compiled from seperate ones.
But yeah, that's some seriously good numbers considering m00stang dyno, elevation, pump gas, and low boost. CONGRATS
Ask them for a proper dyno plot though, we all want to be even more jealous

Thanks all! The best part is that the tuner went through different cells and adjusted fuel and timing. My cruise and WOT AFRs are super stable.

I've got an explanation for that. It looks like the revs/rpm wasn't calibrated so the RPM scale is squished. e.g. his redline appears to be at 5000rpm and crossover at 3600. If you multiply both by about 1.4 you get the more reasonable 7000rpm redline and 5040 crossover.
and before anyone asks the scale factor doesn't affect the power. just rpm numbers. so Brain that 235rwtq is more like 5k than 3.5k
