pearlhatchiroku,
For a bone stock 86/BRZ these are the AFR figures that I recall:
RPM RANGE AIR FUEL RATIO (APPROX)
1.3K-3.1K 14.9:1
3.2K-6.2K 13.1:1
6.3K-7.5K 12.0:1 (at WOT)
The Valentis are nice but they seem to suffer quality issues as a lot of members are already experiencing busted LEDs so you might want to think twice.
