Custom Tuning The 2015 Mustang EcoBoost To Make Big Power!

2015 EcoBoost Mustang Dyno

Our friends over at SCT have been working in conjunction with Bama Performance around the clock to squeeze power out of the 2015 EcoBoost Mustang! You won’t believe the power Bama and SCT made with just a tune… The 2015 EcoBoost Mustang has been the center of attention in the tuning world as it is a fresh engine platform for the Mustang community. SCT has been working non-stop on tuning the EcoBoost and has shared their preliminary results with the Bama Team.

Stock vs Tuned EcoBoost Dyno Numbers

Stock horsepower and torque on the SCT Manual 2015 Mustang EcoBoost came in at 231/288 respectively. The horsepower number can be a little off-putting considering how other reported stock horsepower numbers where in the 270-280 range (see below). Bama head tuner, Paul Meister, explained that the ECU is heavily controlling power output under certain conditions that you will see torque remain the same but horsepower dip off. This drop in horsepower occurs in the higher RPM range, typically above 3500 RPMs. We also tested Bama’s 2015 Automatic EcoBoost Mustang on the dyno and the results are below as well.

With that in mind, SCT came back with 266 HP and 334 TQ with some tuning. Overall that is peak gains of 35 HP and 46 TQ. Gains through out the curve hit as high as 75 RWHP and 58 RWTQ.

SCT Stock Horsepower: 231
Bama Stock Horsepower: 258
SCT Tuned Horsepower: 266
Bama Tuned Horsepower: 283

SCT Stock Toque: 288
Bama Stock Torque: 277
SCT Tuned Torque: 344
Bama Tuned Torque: 342

SCT Peak Gains: 35 HP / 46 TQ
SCT Curve Gains: 75 HP / 58 TQ

Bama Peak Gains: 25 HP / 47 TQ
Bama Curve Gains: 44 HP / 66 TQ

Bama Performance’s Turn to Tune!

Today the Bama Performance team put our new 2015 Mustang EcoBoost automatic on the dyno (pictured above) for some baseline testing before custom tuning. It put down a staggering 271HP and 290TQ on a mix of 87 and 93 octane left in the tank. Check out the dyno results below:

The horsepower and torque obviously wasn’t being limited by the computer in this run and was a much higher base number to go off of. You’ll have to wait a few days to see the finished custom tune results from Bama…

What This Means At the Track / On the Dyno

On the stock tune settings, you may see inconsistent power numbers or track times due to the limiting of power that Ford programs into the factory PCM for many different reasons. If certain conditions are met that trigger these limits, your 1/4 mile pass or dyno run will see a reduced horsepower number as well as slower E.T.’s. This is why having an aftermarket tune from Bama Performance is necessary to get the most out of your EcoBoost Mustang and consistent power every time!

Currently Bama has some tunes in development to not only remedy the power drop off, but to also increase HP/TQ overall, giving you more enjoyment behind the wheel on the street or the strip! The 2015 Mustang Parts list is growing by the day and Bama Performance is hard at work figuring out tuning strategies for the 2015 Mustang. It seems like a Bama tune and a Bama SF4/X4 tuner is going to be one of the very first mods for EcoBoost, V6, and GT owners alike.

    1. For every five hipsters driving Ecoboost cars, there will be a young tuner. And that will be a worthwhile price to pay.

      ‘Cause there’s going to be hipsters anyway.


  1. I wonder if the difference between the observed power of 231/288 vs the reported 270 hp was due to the rating method? Does the factory rate hp at the flywheel still, or are the doing like all of us and measuring at the wheels? Respectable tuning gains though!


    1. All manufacturers release specs on the engine output (flywheel). All of ’em.

      When tuners release information such as the peaks of the output map for a dynamometer, they’re very clearly measuring the output at the tires. Sometimes tuners will estimate the loss in output based on the drivetrain, but this isn’t readily trustworthy information unless someone’s gone through the pain of dyno’ing the engine then the whole vehicle to see exactly what happens.

      Assuming an 80-85% drivetrain efficiency (typical for RWD vehicles), this means engine horsepower output is around 270-290bhp stock, and AM’s tuned version at around 313-333bhp. So, ya, not bad at all for a quick tune.


      1. Good points. Those flash-tune numbers show a hell of a lot of promise for the new Mustangs. I can only imagine what might be on the horizon for the 5.0 . These are good times to be alive if you are a car person!


  2. Just because you drive an Ecoboost doesn’t make you a hipster. If you are young and don’t enough money to get a GT, an Ecoboost is great for you. You get a lot of power and great gas mileage, it’s the best of both worlds


  3. Does the difference in SCT and Bamas stock hp and torque have anything to do with the manual vs automatic transmission…?
