Dude, That is simply mind boggling. Blows me away. I don't know how much these motors can take right out of the box but that's some serious numbers on any dyno (unless the numbers are inflated somehow, sometimes corrections factors will do this, not saying this is). I really like the shape of your tq/hp curves. Doesn't die off like many I've seen recently. That thing is tuned with precision. I guess it has to be at those levels. Good luck with it.

Sledge only recorded 915rwhp on a DJ when we retuned it, it would go into tire shake on the dyno, so we turned it up on the street, that is when we ran the 4.25 60-130, I think that is the only way we could compare these two cars.

That is serious power Dave, congrats!
Being a dynapack, it is sorta in a league of it's own because it measures the power at the axles with no additional rotating mass such as wheels, tire slippage, so in that respect it is likely more consistent. Not sure I could give a blanket conversion percentage for what your car would make on a mustang or a dynojet or the like.

Also, when I say accurate it is not to say that the number it gives is better but rather that the results are more consistently repeatable, giving a better view of how much power you've actually added via mods or tuning when you dyno again and when comparing to other cars dynoed at the same place. Tuning is the only useful way to use a dyno plot given that the day's conditions and calibration of different dynos can result in wildly different numbers even for the same car, make comparing different dyno plots from across the country an inexact science at best.
So when will anyone understand that dyno numbers are arbitrary? Run it in the 1/4 mile to show actual power. Please no 60-130 times.

Ultimately it wll boil down to real numbers but this dyno is the real deal. Maybe not as much as a Mustang but it is putting out some massive power. You can't deny that. You also have to look at the reputation of the tuner. How well known is the person, is he known to inflate numbers, validation with street times, etc....

Dynapacks, while generally considered more accurate, ON AVERAGE read about 8%-10% higher than Dynojets and about 15%-20% higher than Mustang dynos, partially because the drivetrain loss of actually turning the wheels and the losses caused from transferring that power from the tires to the roller are no longer there. That said, Dynapacks can be calibrated to give Dynojet numbers, so those percentages up there aren't a given. You can make a Dynapack or Mustang read anything you want by changing the load values.

Forget all the numbers because they just cause controversy in the end. Forget it all. If it is a number it is too easy to say it is larger or smaller than another, we have been taught this since grade school. Sometimes I wish I could just post a dyno graph with no HP or TQ readings, just the curve vs rpm.
How does the car feel, are you pleased with the end result when you are driving it? At the end of the day, for most people, that is what matters most.

If you are already at 983, I would insist that he break 1K before he sends it back!
No emphasis on "break" mind you...

Rep Power: 244 Point well taken, tho. 
If anything, I'm moving the dial back.
