I just installed a A/F gauge in my friends 91 N/A, I think its running at 14.7 The only thing he has done to it is a big K&N filter. Is that good?

is that under full throttle? Thats stoich, s/b that at cruise/idle. I've always been under the impression that those are unaccurate, if they were why would be use wideband o2s?

it might be off just a skosh. Those tend to not be the most accurate things in the world. Try reading the voltage of the o2 sensor.

hey i can do that on my turbotimer, hehe! wonder how accurate that is, the function is a/f ratio, I will compare it against the dyno's wideband. Sometime in the future
