AFR is not the only parameter that should be used. Tuning is an iteration process and parameters such as EGT, Torque curve, WB02 (if you have one) help complete the puzzle. If your at 12.5, but peak torque with headers, intake and cat back exhaust is still lower than stock, you know you certainly HAVEN'T reached optimal AFR and are still lean. Peak torque will without a doubt be higher than stock, afterall your increasing volumetric efficiency. Start from a point at which you know is rich and lean until you see torque start to drop, richen a bit and this should be close optimal.

Dayum look at those OEM headers.. stillen probably replicated their design but used stainless steel instead and made them look shiny. Those OEM headers are already equal length.

^ ouch! The idea of headers being pointless even after a tune is starting to grow in me

forget the fact that they're rusted and beaten the crap out of.. they look pretty sport and tuned to me

but you didn't dyno the headers by themselves..couldve been your other bolt ons

I've got Cobb helping me with a custom tune in the next couple weeks, and I'm going to do a before and after dyno to see what kind of power can be cranked out with my mods.
I made a lot with my accessport on my last vehicle and it was extremely safe as it was on the richer side.
