What do you guys usually do to set your base Air/Fuel mixtures?? I have an AFPR. Looking to do this in a very simple manner without having to go to the track for tuning.

That's usually controlled by the computer, it will read the O2 sensor and adjust for the correct AF ratio. However when the computer senses WOT, it does not get readings from the O2 sensor, and then it relies on tables and the comptuer and readings from its sensors to calculate the correct AF ratio. Generally, a car runs a little rich at WOT. If you want to change the values a computer is shooting for, then you'll need to buy or burn your own custom chip.

If you just want to see what the AF ratio is, just buy that autometer gauge for $50. Edelbrock and some other companies also make these.
