It seems that some months ago I was on a thread here or club na-t and was talking about the new apexi neo not working with karmon vortex or 2JZ-GE engines...... I think it talked about apexi having an upgrade where you had to send your neo to apexi to get something done to it to work properly. I might be crazy but I somehow remember something about this. Please enlighten me or educate me on this! I would really appreciate any help!
