Do Timing Changes Afffect A/F Ratios
Tuned the A/F ratio on the dyno. I wanted to take the car out on the street to test timing under load. If I add timing, will it affect my A/F ratio? Thanks in advance for the help.

No general rule of thumb as there are way to many things to consider. It depends on many things like where you are already at in timing, if you're experiencing any spark knock, where your A/F was already etc...etc....
