Air fuel ratio

jgibby · April 7th, 2009, 11:41 AM

"m taking the car to the dyno today for 3 pulls on the wideband. I just installed kooks long tubes and catted x pipe so I just want see what kind of power i'm making. I spoke with Brenspeed and they said they guarantee I should have no issues with air fuel since they have experience tuning hundreds of cars with similar mods as mine. I just want to be sure... Does anyone know what the ideal air fuel ratio is for these cars so i know if i'm in that range when i get my wideband readings.

I'm guessing your running the Brenspeed canned tune with the supercharger, if that's the case I would expect your AFR to be around 11.0 to 11.3 on a conservutive tune.
