Does a tune do anything if you don't change anything else?

I am new to Mustang and tuning. I do not really want to change anything else on my car at this time but I am curious if a tune can improve accelleration and/or mileage. I will likely eventually change my gear (not loving the 2.73) but I will wait until warranty is out. I like the sound of the stock exhaust - not a fan of loud. I have heard from numerous sources that CAI doesnt really matter without changing exhaust and other stuff I dont want to get into. So- is it an all or nothing situation or will a tune, alone, make a difference?

A tune will add some HP/torque, and maybe better MPG(slight without mods) but you would be better served with a tune after bolt ons.

A re-gear will not necessarily void the warranty. The ratio's that are used in these cars are too high. The higher the ratio (lower the number) the stronger the ring and pinion are. Weak isn't getting into the mid 5's with large tires and high horsepower, mainly in the off road community.

Re-gearing will void your warranty in terms of your rear end but may not void other parts of the car.

As far as these cars being too high of a ratio from the factory not necessarily so. 3.31 is standard and still gives my stang good to great acceleration. With POS stock Pirellis and just CAI, catback, and 93 BAMA tune I did 4.3s 0-60mph while burning through part of 1st and part of 2nd. That's without LCA and relocation bracket. Just Eibach sportlines. I might actually go back to my stock rims. My Shelby CS40 20" set actually made my car .2s slower with Nitto 555s.

And I can log 29-31mpg on purely highway driving if I gauge closely.

OP has a 13 V6 conv which isn't a slug like the older v6s. I'm not sure what you're trying to say about mid 5s and bigger tires and such. Please clarify.

What the **** are you talking about?

OP didn't even ask about gears, he is asking if its worth it to get a tune if everything else is stock.

OP, yes a tune will help you even if your car is stock, but it will benefit even more with other bolt on modifications. However, a tune will void your warranty pertaining to the engine... If something happens with your suspension or transmission they will have to prove that the tune caused it, which is unlikely.

First, welcome! You're definitely going to love your new Mustang. I'm assuming you have a 2011+ V6 Auto with the 2.73 gears? If so, you're starting off with one of the highest-horsepower V6's they've ever put in a Mustang and a transmission that can perform like crazy!

A cold air intake is definitely going to be something that will wake up your Mustang in a big way. It adds throttle response, gas mileage and helps the engine breathe better. Because the factory airboxes on 2011+ V6's aren't all that restrictive, the gains aren't monumental. There's definitely a difference, though - as we've shown in our back-to-back tests.

The biggest gain will be from adding a custom tune along with the air intake. You'll notice a ton of throttle response, firmer/faster shifts, even further MPG gains and overall you'll add as much as 30RWHP on 93 Octane. We can tune for 87 octane all the way up to 94 octane, depending on what you have available to you!

Each tune we create will be built from the ground-up specifically for your Mustang. You'll let us know what style of driving you want to tune for, what octane fuel, what your mods are and we'll load them up and ship them to you ready to drop-in!

Eventually you can change to a 3.55 or 3.73 gear and you'll notice a huge difference! If you do the 3.55's, you'll notice a big change, but still retain a lot of fuel economy. The performance benefits and getting "out of the hole" will be huge, though. Take a look at our 2011 V6 Mustang Project Car and I think you'll have a pretty good idea of things you can do. We took the car into the 11's (the first in the 11's) with a supercharger, but along the way we built it from the ground up and started with a CAI/Tuner and gears!

Hope this helps. You know where to find us if there's anything else at all that you need!

sbbamafan,

A custom Bama tune will absolutely yield results with a bone stock Mustang. The Bama Team is able to manipulate all of the parameters in the factory PCM with their tuning software. In return, you'll experience increased HP/TQ throughout the power band, increased throttle response, and even a slight increase in economy when cruising. Plus, if the Mustang is an automatic, all of the shift points will be tweaked or firmed up accordingly.

Also, if you're not fond of the 2.73 gears, you could always switch to a set of 3.31's. If you're dealership installs the 3.31's, they'll be able to recalibrate the speedometer and the drivetrain warranty will still be active.

That being said, if you do decide to pick up a Bama tuner, you'll have the ability to switch to any gear ratio you like. Our Bama tunes can calibrate the speedo appropriately, regardless of ratio or tire height.

Give me a shout if you have more questions!

Shane
