Well just for the sake of conversation I went and compared COBB's 2015 Mustang dyno vs COBB's 2015 STI dyno graphs just to see how they looked overlayed (Stock & Stage 1). I know this isn't a direct comparison to what we will see from the RS since it is supposed to have some different components and will have different drive train losses compared to the Mustang, but what else am I going to look at right now?

Here is the stock graphs with the Mustang in RED and the STI in BLUE

Good to see the low end gains, very similar to the way the ST's gained from the tunes. It definitely will be nice to put all that torque to the ground for once.

I would love to see a comparison once one of the tuners such as Panda or Stratified get a hold of it.

The STi hasnt been updated in a while tho and is due. Still holds up strong to the 2.3 nonetheless

Pretty impressive for just a tune.

That mustang torque though. Insane but it's also interesting to see that straight curve throughout the powerband in the stock tune.

393ftlbs of 'merican torque! From a 4 banger. At the wheels.

Some may have already seen this, but impressive times with just a tune!

Thanks for posting these! One of the best things about the RS is overlooked... For the next two, difficult, patience-testing years - I'll at least have comfort in knowing the engine will be pressed to it's limits and almost ready to go upon delivery.

Popped the hood on a new 2015 EcoBoost Mustang yesterday to get a closer look at the 2.3L

If and when I get an RS, I think the tune will be the only thing I get like I did with the ST.

I've been happy with just the tune on my ST and how it improved the overall feel of the car and engine response. Plus, the tune is easy to uninstall for warranty work.

Tunes for the 2.3 are yielding excellent results, the RS should have even more gains with a tune as well. My goal for the RS as of now is around 400WHP but with AWD if more power can be achieved with out sucking me dry I will go for it. I'm sure many people will be happy with just tune or even stock levels.

I had not seen this and my mind is blown right now...mid 12s from a 2.3 4 banger stage 1?? I seriously just creamed my pants thinking about the RS potential.

 

[SyncTheory13]

Think that's cool?

World's First 11 second 2015 Mustang EcoBoost! World's quickest and fast...:

 

[KingZee]

absolutely insane

 

[KingZee]

I'm so curious to see what the RS weighs...if it comes in below 3300lbs I'm seriously gonna lose my ****.

@SyncTheory13

Are some of the folks at Ford trying to debunk the theory, "THERE'S NO REPLACEMENT FOR DISPLACEMENT"? LoL!!

 

[Smokin' Joe]

Gotta take the drivetrain loss from the AWD into account, but those are fun curves either way. Stage 2 is such a blast for how cheap that kind of power is.

Agreed about the pro tune difference. It can achieve greatness
