Around the same. if it starts going leaner then youre running out of gas which is bad

13.2 is just perfect for n/a.

with nitrous, u should be running around 11.5 or richer for safety's sake, not to mention decrease timing if possible.

Your afr for n/a isfine. On the bottle, the 11.5 is a little fat, but not bad. If you canpull timing, then you could lean it out yo around 11.9.
