This would affect LS3s also
The LS3 tune is completely different than the L99. Remember the L99 has Variable Valve Timing and Cylinder Deactivation...

That will require completely differents tunes/programs. From what I've been able to learn from some of our insiders. This issue is only found in the L99 tune.

FWIW

Welcome back BTW!
