There was a fan on when this pull happened. The guy doing the dyno didn't start working with the fan on. The point i was trying to make was maybe this wasn't the most professional set up. But in NJ its hard to find a dyno, we drove 50 min to get to this one.

That 4th gear dyno is cut short by the speed limiter. I think the pentastar makes about 220 whp. UNCORRECTED. I think you can expect more like 65 whp increase from stock with my numbers.

The magunson dyno shows a better power gain.

Is it because my numbers are the 4th pull of the day? Poor ventilation?

I don't know. but for reference I wanted to give you guys what I got.
