So basicly what I'm asking is what can I use on my Max to tune the A/f ratios. I know there is the Safc2 (super air fuel controller) and the wideband thing? What about an aftermarket tuning software.

I know our nissans are picky as hell about what software will communicate with it. Nissan datascan, cipher all them things but would an.afternarket one work? Like say have somebuddy right me a program and tune it for me? My list of mods are getting up there so I'm prolly needing a tune to optimize the mods. Looking for input, best routes, suggestions and what not. I know I'm running rich I can.smell it but I'm still pulling 31mpgs mixed highway and street
