HP bump in SLS GT
With the SLS GT, how did MB obtain the extra ~20HP over the 2011/12 SLS?
1. Just a retune of the ECU?
2. Different engine internals?
3. Something else?
I'm thinking it's #1 but this is difficult to confirm. Besides this HP bump and the adjustable suspension, all of the other GT updates were cosmetic - correct?

The adaptive suspension in the 2012 models had 3 settings. In the '13 '14 '15 it dropped down to 2 settings. Not seeing how less is more in this case.
From C&D
The newly powerful engine makes maximum horsepower at the same 6800 rpm as the outgoing version. That increase comes via the manipulation of timing, fuel injection, and spark to improve combustion. Despite the power gain, the improved 6.2-liter’s torque production remains at 479 lb-ft. All that backside-compressing power is fed through the same seven-speed, dual-clutch automatic as the previous model. However, the transmission receives new gearchange logic paired with updated engine mapping, which Mercedes promises results in quicker shift times.
The previous-gen Adaptive Suspension is swapped out in favor of AMG’s new Adaptive Performance Suspension, featuring stiffer and more aggressive spring and damper tuning for both of its two modes. The stiffness being conveyed through the even-stiffer-than-before suspension is met at the other end of the equation by standard matte black/polished face (three other colors will be made available), 19-inch, 10-spoke aluminum wheels at the front and 20-inchers in the rear.
