Best Fuel Pump Advice for Newb...

Guys - To keep this short, I changed it from 0.092's to 0.095's. The AFR's would run about 12.7.

I then changed it from the 0.095's to what's in it now which is 0.098's. The AFR's are now hitting about 11.7.

I want to run it down the strip tonight. My target AFR is 12.2. Am I better off with 11.7 or should I go back to the 12.7? It's going to get a bit chilly tonight. I'm thinking I may be better off with 12.7, and colder temps may pull that down a bit more.

Input appreciated.
