Winter fuel economy/power

Colder temperature making for increased charge air density is completely true. This is why I have trouble understanding why I observed the decrease in power when i was expecting an increase in power (also substantiated by the observed power numbers with the Haltech ECU).

I am still hoping that someone on here knows the stock AFR in cold conditions. I have a wideband O2 sensor, but is is on the '86 which is getting a turbo transplant and will need the wideband.

I can't use it on the '91 anyway as it is snowing in Wisconsin and I don't want to drive an RX7 in the snow if I can avoid it.
