SLS-Engine internal differences

What are the internal engine differences between the SLS, GT and BS ?

Could be just more aggressive factory tuning ? Tuning and exhaust manifolds ? Cam profile ? Cylinder heads ?

Shocking that nobody can answer this !!

I've got to believe the answer is the only difference between the SLS, SLS GT and the SLS BS is the tuning.

If I remember correctly, the SLS GT has a revised intake manifold and tune, while the SLS BS has vastly modified valvetrain and heads on top of a tune. Hope that helps!

I think the SLS GT is just an ECU/TCU tune.
