If you mean, re map the air/fuel curve, then the answer is yes..As for wot ? I would say the optimum range, should be between 12.5 -12.9 maybe even @ 13.1 but, no higher..Otherwise you may end up having pinging issues and posible detionation probems.. Although bear in mind, I'm not a technician or tuner, so all I can provide is an honest opinion..
