Dyno vid today...dynojet numbers...confirming that the estimates were pretty damn close. I didn't run my power tune until the second run (tried the DD tune first), so I probably would've been another 5whp or so closer to my original shootout guess of 583, still 570 is pretty damn good i think.
My DD tune pulled 525 whp!
