actually yes every dyno is different even those from the same company apparently...i read that graph above from razorlab...at 50mph i was 15.1 hp n i dont have injectors that can be utilized w/safc im only stock 525cc so why is he at peak power 30 hp/tq above me?

I think you should also post the boost that the car did or boost graph if you have it.
It makes a big difference on what hp to compare to.
I own a mustang dyno and have alot of customer's graph, but I can't just post it up here.
I leave that to my customers.
We now have a shop evo to play with so can post those graph shortly to compare.
As for Mustang dynos putting out different numbers, its true, but not a significant amount.
If each dyno is ran through a certain test, you can find out if the load weight their using is the one programmed for that dyno.
Theres also the multiplier thats is used to calculate for different weather conditions that sometimes altered to read higher number.

Here is what I see on this topic. Great idea but it is not going to work out well. Let me explain.
I use to own a Dynojet. The Dynojet is actually harder to manipulate than the MD dyno that I have now. As long as one Dynojet shop used DAE, STD or Uncorrected numbers and the next shop used the same (preferably SAE) both shops would be very close.
The MD on the other hand has a bunch of ways to change the readings and to be honest I think at this point each and every MD owner I have seen has changed his or not used the recommend weight and HP@50 mph numbers. So comparing charts is useless.
MD has a "Look-up Chart". Some of the MD owners out there probably do not have the newest version that has cars up to 2005 in it. I do as I just bought the dyno. When you dyno a car the operator is suppose to look up the car in this chart and it will then give you the weight you should input and the HP it takes for the car to travel 50 mph on flat ground. In this chart for 2003-2005 EVO's is says 3625 for weight and 15.1 for HP. Now I know and you know 3625 is heavier than a stock EVO. However it is not heavier than a stock EVO with two guys like myself it in, that would be a little on the light side at that point. I have moved these numbers around higher and lower and it does make a difference in the HP the car produces, not drastic but does make a difference.
Now the one input that does make a HUGE difference is the "roll weight" this is a hidden parameter that you have to go and change and nobody knows it was changed. When my dyno showed up it was calibrated to 3333.57 pounds of roll weight. By changing this number the power is effected DRASTICALLY.
You now know the settings on our dyno. We have the MD500 AWD SE dyno. For any EVO we put on it we input 3625 for the weight of the car HP@50mph=15.1 and our AWD roll weight is 3333.75.
This 3333.75 could vary from dyno to dyno as it is the weight of the belts, interia weight, bearing drag etc.
A stock 2005 EVO on our dyno will make between 200-215 for the most part.
