Are you sure this is an EFI issue and not blown collector gaskets? I was chasing this issue last summer and along with with blown intake gaskets. My collector gaskets were completely blown (on an SPF the tell tale sign is carbon soot on the polished reflective heat shields surrounding collector flange). Gave me a nice backfire on hard deceleration due to sucking in air. Replaced with the Remflex collector gaskets and all is well.
