UTEC tunning
I'm just wondering what a good a/f ratio is for an 05 wrx with Up/Down pipes, intake, VF34 turbo, 660cc inj, 255 fp, running 100octane all the time. Probably going to run 19psi. I've heard people say that 12.5:1 is the most efficient.

Depends on many factors. Altitude, octane availability and so on. If you don't know what you are doing, richer is safer and better. On the 91 octane urine I get at sea-level, I shoot for 10.7:1 at peak load.
