I can't seem to find AFR or intake temps on mine. Are you guys able to read it with your Boss?

I have the stock Boss grill with the flaux covers still in (not cut out yet)
the air temps in the afternoon was about 91....which I saw in the car.

I was heard Boss goes into limp at 260 engine temps
.....anyone confirm that?
Mine cools 20 degrees just by letting off the gas, I doubt you need to run the heater on a cool down lap. I have heard the limp mode is 250 but I do not know that for fact.

There is a intake temp and it is in one the main menu's and you can set it to your custom page.

I finally found the A/F setting. But it displays Stoichiometric data vs. Lambda. So you would have to multiply that number by 14.64 to get actual A/F. I think if I set the Wideband O2 guage as well it'll display actual or Lambda. I'll experiment more over the next few days.

I also set ambient and intake temps on the same page, it's surprising how close they are with the stock air box. I'll be testing with the Airaid on next.
