AFRs: Idle, Cruise, and WOT
I am curious what AFRs everyone is running via idle, cruise and wot. If you know your MPG as well that would be great.
BTW how many run stoich upto 0psi?

I run with the O2 idle, ISC idle, and timing controls all turned off.
At idle and cruise I run as lean as posible without stumble.
Idle about 13.8, cruise about 14.7 at 35mph and 16 at 80mph.
Low cruise seems to need to be richer than high spped cruise. But I suspect my
8.5 aluminum flywheel has to affect that.
WOT depends on boost, how well your IC cools, and same applies to your radiator, and timing. Also how safe do you want it?
10 psi 11.8
12 psi 11.5
14 psi 11.2
15 psi 11.1
16 psi 10.8
