Yes, our cars have a "learn down" feature that eventually will put the horsepower back to stock levels.

Either way, great numbers! Especially on a Mustang Dyno.

What does "with WCF" mean?

NM weather correction factor.... Those are some hearty figures for a mustang dyno, you gonna tune it soon???

Nice numbers. Even if it was 256whp and 262wtq those are still great numbers for a mustang dyno. I was told that the mustang dyno actually dynos the lowest out of all dynos. I could have been misinformed!

doesn't the stock ECU raise/lower boost to maintain the stock numbers at all weather conditions? If that's the case then the WCF corrected numbers wouldn't be correct.

The uncorrected numbers are spot on, the corrected numbers would be at a lower temp and at sea level i'm assuming...in which case the ECU would lower boost to maintain the stock numbers.

Ok, I am not familiar with good 1/8th mile times, but just curious. Not gonna lie, those numbers are way high, its most likely the other number, but either way, not bad at all!
