My experince with the mustang dynos is that the numbers themselves mean very little as there are many settings the shop can make to the dyno to change the read outs. This is why I like dyno jet there is nothing to adjust and therefore, the numbers are consistant from dyno to dyno.

MUCH more important than the acutal number to me would be the a/f information and the dyno chart itself.

If you can email me the charts or call me to get my fax number. Looking at the charts I will have a good idea of what is going on.

There are many reasons for low power output and the tune is just one of them. With some more data we can trouble shoot the situation and find out what is the cause.

Also - where do you live ?

Thanks

Al's right there. get the A/F ratios and that will tell the story.

I live in wisconsin, and i will be contacting you about the fax number. I also didnt get a air fuel printout when i had the car dynoed

We have a AWD Mustang dyno here in town. One local STI owner took his car down there with a Injen intkake and put down 294whp on it. Looking at the dyno sheet, you can see that the weight of the car wasn't right. They put 3250 lbs. with the driver. That is why it read so high. It seems like theyare trying to get it to read like a DynoJet or soemthing.

I put down 233 whp on a Mustang dyno with just a intake, downpipe, and cat back when I first started modding my car. From what I've read and have been told, Mustang dyno's read about 18-20% lower than a DynoJet. You could probably go back and put down something totally different.

I'd make sure that they put the right weight in for the right load on the rollers.

Yeah, they get the weight wrong a lot cuz it's a pain to weigh every car...what is an avg Evo's ACTUAL weight...I know curb is like 32something i think...but I've heard it's more like 31-- on actual scales, any one know?

I did 290 or so on a mustang dyno with similar mods and custom Dynoflash. Mustang Dynos seem to be pretty random... Were there other Evos there that specific day to compare your results to?

Oh yeah, and i did 208 stock on a mustang dyno set at 3100lbs in 35 degree weather with 91 octane pump gas...just for comparision...did you have a baseline done at the same place? or at least a recent dyno before the flash, that would help to solve this whole problem...like if you dynoed a baseline at like 170...

Yea definitely! Let me in on all the info and dates and we can go take our cars!!

I put down 285AWHP and 300AWTQ on a mustang dyno last tuesday!

Mods: HKS hi-power catback
UR 3" TP
MBC@21.5 psi
Flash

I was still running a little rich up top. I still have the stock DP

They probably have your weight wrong too.

When my customer pulled 357 tq on a evo with stock cams at a dyno day in Texas everyone was crying about how the Mustang dyno can be manipulated by the numbers you enter for weight, gear ratio, etc etc. The mustang dyno is a great dyno for tuning but you have to take the numbers with a grain of salt, they do not mean much unless you are making an A - B comparison on the same dyno with same settings.

My thoughts on this are the following:

1 - Without a base line the number means little. Heck this is less than stock evos make on our dyno jet and this guy has some mods. Obviously the dyno is calibrated wrong or the car is not operating properly.

2 - There are many possible causes of weak power output and the tuning is usually NOT the cause in my experience. I did not wrench the car or install any of the parts, it is quite possible that a boost leak, inaccurate boost gauge or other mechanical issue may be effecting the power. A good 40% of the cars that come to my dyno have one mechanical issue or another which needs to be fixed - some of the most common - mis reading boost gauge, boost leak, bad boost controller, spark plug mis fire, leaking bov - just to name a few.

3 - When a customer has a problem, I would expect them to call me first and let me know what is going on so MAYBE I can help them to find the solution - which MAY involve trying a different tune - depending on the results of the dyno sheet how it looks and the a/f ratio. I find it stange that this customer choose to never contact me - instead he contacts tubro tricks and makes this post. We are here to help customers out oif they have any problems. I read and respond to dozens and and dozens of PM's emails and voice mails a day and spend most of my spare time at night talking about evos on these forums. It seems very strange that if someone had a problem they would not contact me first to see if there was a way to work about it or improve the situation.

4 - With my mail in flash it is virtually impossible as a matter of pure physics for the car NOT to pick up some power. Simply put the stock tune is so weak and under tuned there is almost no way as a matter of mathimatical laws and physics to make LESS power with the reflashed ecu. Now - in 90% of cases mail in flashing yields very good results, BUT as everyone can read it is not my most recomended path of tuning. In ALL cases custom tuining has shown to pick up power over base flashes. Simply put the through the mail base flashes MUST be de-tuned by a set percentage over custom tunes to safely provide a window of operation fro car to car variance and variation in fuel supply. Those who tune more agressively on a though the mail flash risk engine damage and knock. I have tuned over 1,000 of these evos without any examples of tuning related engine failure. I can deal with someone saying they thought they would make another 10 - 20 whp - I CANT NOT deal with guy's engine's blowing up. With that said - it is virtually impossible to conceive of someone not making additional power with our through the mail flash over the stock tune. This is why we promise you at least 20 whp or your money back. For the $199 it costs the through the mail flash is a great option to provide people with a wide range of modification paths an individulaized tune which matches their particular mod combo and affords a smooth enjoyable and safe power band. There are lots of very happy people out there with my product and who have had great results and there are a few who are not happy.

Anyone who believes that another flash tune made Evotexas 100 additional whp over my flash needs to put down the crack pipe.


5 - The reason why I offer a two week test drive and a full money back guarantee is so that people can try out the through the mail flash and see if it works in their particular case. We have hundreds and hundreds of people who have purchased the through the mail flash and have reported excelent results both on independant dynos and also at the track. In fact we have almost 10 guys in the 11 second drag club now with either the flash alone or the flash and afc. Those who try it and do not feel a good response can just send it back for a full refund without questions.

6 - In almost every instance of those bashing my product on line and attacking me personally there is some affiliation or connection with another tuner. I fiond that these people are usually posting peak dyno numbers ONLY and not an associated dyno sheet with a/f print out. To me a peak number without the dyno sheet is totally meaningless. Also - whp made with lean a/f ratios which results in knock activity and pulling of timing is not of much practical value in driving on a road. I have posted dozens and dozens upon dozens of dyno sheets, case studies and other actual meanginful data about my tuning on my section of the vendor forums. I find that the people who are bragging about making HUGE POWA on their dyno pull ususally hav lean a/f, knock and a rough power band. All I can say is buyer beware of this type of content devoid boasting marketing tactic.


Thanks for your time in reading

Oh my God, yes that's low. Here's a comparison of your mods to mine

----------YOURS------------------------------------------MINE
255 LP Fuel pump-------------------------------255 LP Fuel pump
Hallman MBC------------------------------------- Hallman MBC
Helix HFC and Downpipe-----------------------Megan HFC and Downpipe
Greddy Titatium Exhaust catback-------------Helix Catback Exhaust
Aem Intake----------------------------------------Injen Intake
Dyno flash through the mail--------------------TurboTrix Flash
boost is set at 20 psi----------------------------boost is set at 20 psi
HKS Blow off valve-------------------------------MR Blow off valve

I also dyno'd on a Mustang and pulled 295.9 WHP. Find out when TT is gonna be in your area and have Mark give you the power you deserve with those mods.

Turbo Trix all the way.. look at my mods. ........

Al, you clearly didn't read my post very well based on what you just posted. I said I wasn't comparing your old flash anymore because I have more mods now and have moved on from all that nonsense, which is why I have 100 more hp than when I had your flash. I didn't say I got 100 hp changing flashes only. I did gain 50 though. Sucks for you as it may be.

Comparing Dyno's is stupid. They all could read different, especially Mustangs. Case in point, up here we have 2 Mustang dyno's and 1 reads about 80hp more then the other. One guy thought his car was super strong (350hp) until he was dyno'd on the other one at an EVO dyno day and put down 270hp which was 15hp less then every other cam'd EVO. It turned out the installer didn't install his cams correctly.

So the moral of th story is, to get a baseline from the dyno operator what other similar equipped EVO's put down.
