As the title says I'm looking to tweak my tune a little. I have a 05 sti with gt spec uel headers and uppipe,full exhaust,aem cold air intake, walbaro 255 pump, turbo xs rfl.. Running cobb stage 2 map with my wideband installed I noticed it runs 10.0 air fuel ratio which seems to be way to rich for me.. My question is which screen would I go into to kinda lean this put using access tuner race ??
