No I dont have a wideband O2. I do work for a tuning shop with a dyno and a wideband and can use it when ever I want to. On my last runs @9 psi I saw 12.8 to 1 air fuel ratio. Almost on the lean side, that is my I felt I needed a bump in fuel pressure 45psi. I haven't had the chance to get the dyno since the fuel increase, but look for more threads on this in the near future.
