Hey Guys - I'm sure you've seen that the Bama Performance Team has been hard at with their 9-Second S550 as well as their new and improved V2 Tunes but they're just now wrapping up research & development on their Automatic Tunes. We just recently brought on an automatic 2015 GT and in bone stock form it was able to best some pretty solid numbers 361 RWHP and 342 RWTQ While they're respectable figures the Bama Performance Team wanted to focus on making some more power along with cleaning up the driveabiltiy.

The guys at Bama wanted to dial in just how the power was put down and they made some really dramatic changes to the shift profile in order for their customers to have more crisp shift points, a greatly improved and more aggressive throttle response, and again better driveabiltiy on either WOT or just getting around town!

On 87 Octane and a Bama Performance Tune the S550 put down 372 RWHP and 344 RWTQ and swapping from 87 to 93 octane they saw some really incredible gains to the tune of 393 RWHP and 377 RWTQ!



Just to give everyone a better idea on this again these gains we're all made with the Bama Performance X4 Tuner


Stock RWHP/RWTQ: 361/342

Tuned RWHP/RWTQ: 393/377

Peak Gains RWHP/RWTQ: 32/35

If anyone has any questions don't hesitate to let me know!

Impressive gains for stock + tune.

 

I couldn't agree with you more! These cars really have a lot to offer any it's amazing to think that with just a Bama X4 Tuner that these numbers are possible. Mind you that this was done without a Cold Air Intake or any other support modifications!

If anyone's curious what this looks like here's a video riding shotgun last week

 

I also noticed that the new power and torque curves are the same shape as stock, but look smoother.
