John made the few hour trip out this morning to get his stock 2008 Evo X GSR of the graphite gray variety tuned today. His car was otherwise stock outside of some lowering springs. There were only about 3k on the odometer as he had just purchased it a week or so ago and what better way to break it in than to custom tune it on the dyno!

Off the bat, John's low mileage 4b11 appeared to be free from the stock misfire that has plagued so many Evo X's since their release of the car. It appeared to have been equipped with the latest dealer reflash which seemed to be the reason why it was able to make a clean pull in stock form for once.

Nevertheless, John's car continued to impress us as we went to work tuning it. Starting with our dynoproven mapping developed over the last year of custom tuning the 4b11 in house over and over again to perfection, it was not long before we had her dialed in.

With the first pull, the car gained 60whp or so, up from the baseline.

Next revision gained another 5whp or so.

The final pull gained another 9whp, settling the otherwise stock car at 347whp!

Here is the overlay from baseline stock to custom tuned:



Here are the raw numbers before and after.

 

Sick numbers

 

Awesome
thanks for sharing.

 

Nice.

Are these baseline numbers typical for a stock evo x on your dyno? (around 280whp/290 lb ft)?

 

So stock Evo X make 280whp and 289whp torque on your dyno??

 

This low mileage Evo X had the latest dealer reflash which leaned out the car to 10.0 in stock form which is much leaner than we normally see.

It seems that either the boost control solenoids or the wastegate actuator preload can differ from car to car. We have found that some need a restrictor pill and some do not. This car was one of the ones that had nice range in the BCS control possibly from a little stiffer wga setting from the factory. We were able to achieve 25.5psi peak tapering to 18psi which usually requires some help in the restrictor pill department to achieve that level.

Lastly, we did not see the typical misfire in this car which we have seen in nearly every other Evo X tested. It seems the latest dealer reflash has this leaned out to the point that it can fully ignite the fuel mixtures.

As pictured in the graph, the stock mapping was on par to make about 258whp until the last 500-1000rpms where it jumped up 20whp. I haven't looked at the original mapping but there may be higher timing in this area on the newest dealer reflash to help cure the misfire.

 

thast a high baseline number, but a very nice after result.

 

So is it plausible for someone to hit 400whp on your dyno with a stocker?

Hey Meat!

 

No. We have tuned Evo X's to 35psi and racefuel to 380's.

Our dyno reads lower than Dynojet 424x and the other Mustang Dyno AWD-500 in town.

 

Thats nuts. I'm hoping to get that tuned on e85 with i/tbe/injectors/and more boost.

 

Look at the gains...approximately 70-80whp gains and 50-60 wtq gains. Curve looks good and TTP did a nice job. That's right in line with the gains other tuners are getting with a bone stock Evo X.

Also, be careful when reading peak numbers on TTP's dyno. Their dyno reads much higher than other vendors on this site. Nothing wrong with their dyno. It just reads high which is why gains are more important than peak numbers.

 

Our dyno is lower reading than Dynojet 424x and all other Mustang Dyno's in our city.

We use a weather station for true SAE J1349 numbers. Some other dyno operators do not use a weather station so they can have abnormally low or high numbers, depending on the weather, temperature and humidity whereas our numbers are consistant regardless of the weather.

 

Gains look good.

Baseline is incredibly high compared to all other shops I see on here. However, it is consistent with baselines of cars coming out of your shop.

The other dynos in your town must be improperly calibrated as well.

 

Actually you are incorrect as MustangDyne flew in an calibrated the dyno themselves. The manufacturer of the dynamometer calibrating their own product insures its accuracy.

 

+1000

If other people are not using weather corrected numbers the numbers will typically be much lower as the density altitude (correction for pressure and temperature) is usually 1000-2000 feet in FL, which is near sea level, on a hot day. The weather correction will correct for SAE on a standard day.
