Yeah. Considering it is making more power everywhere I'm not sure if richer than OEM is a good or bad thing. I've heard that the sniffer usually read a little low so going under 12 a/f at the tailpipe does sound less than optimal. Thoughts? Does anyone know the target AFR that Evolve is trying to hit or what makes the best power on the S54?
