You're definitely lean at WOT, but cruise, me thinks, is dead-on, which
makes sense because that's closed-loop operation anyway.  As far as the
N2O program, that's what it's supposed to do; feed it crazy amounts of
fuel to burn with all of that spray.

So is that an AEM UEGO?  Did you get the brick or the gauge model?

Also, what's FB%?
