Quick AFR question richest value for my mods=??? @ peak torque... extra points if you can guestimate my peak torque. My cmd'd afr = my afr.. 
Also. I guess im going to extend the question.. When my converter locks up on the highway and I just barely tap the gas I command a stupid rich afr.. Closed loop does not behave like this.. It always commands 14.7 until WOT. I have scaled back IVT vs MAP (open loop fueling). So.... should I scale it back a little more to behave like open loop? Sometimes I'm seeing cmd'd 14.10 in situations that should not warrant a richer fuel mixture. 13.90 when the ac is on.
