Hey guys I just did a few runs with the wideband on my sr and im getting a 12.3-12.4 afr under full throttle revving to 7000rpm. The motor is stock with bolt ons. greddy fmic, t25 at 14psi, turbo manifold, 3 inch turbo outlet, 3 inch downpipe, 3 inch test pipe, apexi n1 catback, safc2 and a few other goodies.Timing is set to 13 degrees.

what do you guy think?I'm also going to the dyno very soon to see what kind of numbers it will make. what should i be expecting?

AFR seems good enough, Id prefer a little richer but I dont thing you're too lean, are you running 93 or 91 octance. And Im guessing around 250whp.

I think driving it at full throttle in third gear is a better way of determining your afr's.
