I hear what you guys are saying about keeping it like it is suppose to be etc. Problem is that really ruins my data from the last 5-6 years. Also is going to keep someone from coming back if they use a competitors dyno that reads higher.
The fact is changing this othe parameter did NOT change the tune in the car at all. The AFR's and boost stayed the same. All changing it would do is put it on an even level with other dyno's in the area. Hell there is one within 10 miles of me now and another within 25 miles. One more going in about 1.5 hours from here. Then there is an engine dyno directly across the street!
I can always print two sheets for anyone wanting to compare. One with true MD numbers and one with the Dynojet "simulation" numbers on it. That maybe the best solution.

SloRice,
Thanks for the input, it is appreciated, I love the dyno. The inputs I used are right from the charts you guys gave me with the dyno. The weight and HP@50 mph.
ShapeGSX,
Dyno starts around 9 am Saturday. Track opens at 8 on Sunday.
Scott88,
The numbers you mentioned on the MD there, is that on race gas?
Fixem,
I appreciate the offer for sure. I figure this weekend I am going to get more data than I want! haha. I bet we are on the dyno non-stop for atleast 10 hours. If you want us to do the install on the car I can dyno before and after for you. Just let me know.
No break in on a new dyno, it is run at the factory.
fourdoor,
Good idea on the Stages and re-testing. It is so much work, going to have to be done though. Now I just wish I owned a stock EVO again
Funny seeing some of the HP@50 mph numbers and weights being entered. Mustang Dyno SUPPLIES with their dyno a huge database that gets loaded on the computer. All you do is go to it, find the year, make and model of the car. It then says right there what weight to use and the HP @50 mph. In defense of some of these shops, I think I heard that until just recently the 2003 and newer cars were not on the list.
I think the weight is suppose to be 3625 and HP @ 50 is 15.1, that part is for sure.
We all know the EVO doesn't weigh that much.
I plan to take time this weekend to stand at the scales at NRP and weigh some cars as they come through and take notes. This will get the tunes even closer (if that's possible!). The information I gather this weekend will be what I use for input weight in the future. Just weigh full weight 1g's, 2g's FWD's and AWD's and couple different EVO's.
As a side note I used the standard weight on my RS and then dropped the weight down to what I know it weighs, in this case about 550 pounds less. Had no effect on the tune but did effect HP. I can't remember exactly but I think the power was less by lowering the weight by about 8-10.
This small 8-10 whp change would be fine if you were trying to "trick" someone into thinking you made them more power but does nothing to equalize the MD to a Dynojet number. I think on a Dynojet my RS would make over 400 whp.

tryndex,
Yes, my intentions were to just see what the car would dyno on an AWD Dynojet so I could come back to our shop and change the input until it matched. Then I could keep that number stored and use it for comparisons.
I'll do it, just a matter of a day or two before I get the information.
When I do this I will make the information all public for you guys to know. Hell it may even help the MD owners out if we all atleast have the same information to use.

That was on 100 oct with a Custom Dynoflash and tuning with my SAFC for the race gas and 25psi. A/F's were at 11.8

Dave, congrats on getting a "heart breaker" dyno. (at least thats what all my friends and I call it). Personally I prefer to have my car tuned on a mustang dyno. The real results are at the track as you stated. MZM tuning down in Austin TX has a similar setup, and anything over 300awhp is in the 11s on their dyno. I made 277 on my 2003 evo.
I wouldn't touch any of the settings to get higher posted numbers. Personally, I love it when I beat someone on the street and he asks me how much HP I have...277 to something like 350 or 400 and he can't believe it. Then I pull out the dyno sheet...its like that mastercard commerical....priceless

Priceless........I like that one! haha
I am getting use to the dyno already. Was on the phone with them yesterday getting some information and suggestions on some of the things we have done. Good tech support.
I tuned two more cars yesterday. One gained 45 whp, the other was set up fairly perfectly right off, didn't do anything but adjust the alky, my step dad's Galant VR4. It made 330 on pump gas and alky at 21 psi. Pretty impressive.

Damn it.
I was on the phone with MD yesterday and found that the numbers that we were changing around to see what would happen with the dyno were never saved. I found this by accident actually when I dyno'd a couple of other cars and corrected it.
I was very curious this morning about the numbers we got from my brothers car. As I suspected that when the installer from MD was here and we were changing numbers that when we pulled Dan's EVO they defaulted back to what they were set at the factory.
Well I was right. The dyno is now EXACTLY the way it was delivered and set up. Every single parameter is also EXACTLY the way MD wants it.
Very disapointing, the car made 538 whp and 465 torque. That's a long way from 640 whp.
My brother said, "Just tell me the numbers, I don't care what the dyno says, this is the fastest and cleanest the car has ever run."
I have one car to tune today, one to run for a comparison to my competitors dyno and then I am going to put my RS back on and see where it is.
538 whp isn't much of a number for a stroked EVO, race gas and a GT35R. This car has trapped over 134 mph at complete full weight. The front steel bumper support is not in the car and the car has a 16 gallon fuel cell that is full most of the time as Dan drives it almost everyday to and from work.
I can't wait to get the AWD car on today that was recently on an AWD Dynojet. Then we will know.
Hope you all enjoy reading the trials and such I seem to put everything we do through.
Thanks guys,

Could be worse your customer base could be Supra owners and you wouldn't get any buisness! Et, and Mph are the only numbers I want or care to see when someone is telling me how great there car is. Mph don't lie. 
Dave,
Maybe you need to make a chart of sorts with one or two cars in particular...DSMs or Evos, or whatever you guys mainly tune.
300hp = XX.XX E/T XXX mph
350hp = XX.XX E/T XXX mph
I understand you are running a business and a lot of people want their dynos huge so they can claim they have a big chubby or something, but a dyno is only a tool for tuning. The real results are at the track, and are driver limited. You know this, as most here on this board knows this...but I can understand where you are coming from in a business point of view.

I never got it, why do you guys care about dyno numbers? If I want to know how fast my car is I go run it to see what it will do, thats the number I care about. Showing somebody your dynoslip is like trying to show some hottie your underware so she can get an idea how well your dic* rocks!

Dave, just to second what Karash stated earlier...I've had my car on MZM's MD since I bought the car. Stock Evo's run between 180 and 190 HP. If you're posting numbers in the 250 HP range, the cars run about 12.4 @ 110 at the track. I just put down 372 HP and trapped at 119.6 mph with a 2.4+ 60 and only 85 mph at the 1/8th mile.
The bottom line is when it's done on the dyno, it's 99.9% tuned and ready to go. MZM uses 3400 lbs. and 14.0 HP @ 50 mph. I, like many others in this area, know it's not about the BIG numbers, it's about the tune. What I tell to all who will listen, "get a stock baseline number and judge your progress from that stock number after each modification".

David,
I ran on your dyno on saturday. That was my first time on a mustang dyno. I had dynoed on AMS's dynojet about 3-4 weeks prior, and made 608 whp. Since then I fabricated an equal length exhaust manifold for my car... thats it. I got on your dyno and made 498 whp on my first pull, then the second pull I had turned up the boost to 39-40 psi and spun the tires to 9k almost instantly.
The one thing I was unsure of is why you had us do the dyno pulls in 3rd gear, which for an evo may be closer to a 1:1 gear ratio, but certainly not on a fwd dsm. I have previously done all my dyno pulls in 4th. I also noticed that you had everyones car listed as 3250 lbs. Not sure how this affects a FWD car on your dyno, but I am pretty sure that a dynojet loads the car at roughly ~1900 lbs.
All in all though I wasn't utterly dissapointed, because like many of you have said, the hp numbers dont really mean shi t. My car is in a very nice state of tune, and had I been a better driver
I would have done much better. Sunday the car went 11.6@136 on a god awful 2.1 60' I suck at driving apparently
