Either way...after new plugs, swapped coil pack positions, added catless downpipes, and switched maps from Stg1 Aggressive to Stg2 Aggressive, I'm no longer misfiring. The car feels good, just not quite as quick on the throttle as it did with Stg1 Aggressive.
Did you try Stage 2 Linear throttle or stock throttle?
