I just had my '15 RTX with MPI Turbo updated with the new flash and during my first and only ride of the year it's backfiring every time I hammer the throttle. What could cause this? The Flash? Stale gasoline?
Any help or suggestions will be greatly appreciated.

Causing the backfiring or caused by the backfiring?
