Have you changed wheel or tire sizes? You have to keep the front diameters the same percentage smaller than the rear diameters or the computers go nuts trying to balance front to rear tire speeds.

Can't help with your problem, but I think we saw your car at Abuelos today - looked great! I'm trying to remember the info in your engine compartment (Lethal Performance?). My wife and I are considering supercharging our 08 Coupe, so we're looking at different options. There's supposed to be a cruise in July, so perhaps we'll get to hear your ride in action.
Good luck with your issue - I'll be interested to see if it's tire related or tied in with the supercharger.

That's probably the reason. You went UP from 25.71" to 26.56" in the front and DOWN from 26.85" to 26.00 in the rear, your computer is confused.
Either a smaller diameter front or a larger diameter rear is needed.
