I don't know if I am on track or not... Also don't know if what people are telling me is true or not.
Initially I thought there were Mustang Dynos & Dynojet dynos.
I thought I was getting dynoed with a dynojet... when I got this done.

I wanted to see if my numbers were on par with Kenne Bell's claimed 500+ rwhp http://www.kennebell.net/
They use DynoJets.

I found out later I went to "the heartbreaker" dyno (Dyno Dynamics)
Here's the results:
HP vs. Torque
They then took the number and multiplied it by 1.29 to come up with my Crank HP 471hp\425tq (is this a correct calculation?)
Here's the other Data for:
Boost
Air/Fuel
Dyno Settings they used

So basically Kenne Bell says 500+ rwhp and Dyno Dynamics says 365rwhp... How can they be that far off?
Any other KB guys have dyno numbers from a "Dyno Dynamics" machine I can compare with?

I went in for clarity and now I am just even more confused than ever.
Thanks for any input...
