Since I got my wideband and tuned for 13-13.2/1 a/f, I feel a warmth coming from the dashboard area. It's not extreme heat, and water temp is normal, plus I have no knocks or misfires, it's just that I feel a vague warmth inside the car like the heater is on low (but it's not) is the best way I can explain it. Before getting the wideband, I was a whole point rich, and my theory is that at this cutting edge a/f ratio (13-13.2:1) the engine must be generating heat inside the compartment. Has anyone noticed this with their car? The car's running great, the best it ever has, no codes, misfires, knock, nothing, just this warmth inside the car. Any insights?

Thanks.

BTW, last time I scanned after tuning, the water temp was holding around 202* from around 195* (when I was a point rich).
