LM1 turbo logs, need opinions please

tell me what you think of these two runs. The car is faster in the leaner run, but where should I be in relationship to these logs for normal everyday driving?

The second is better. IMO If you go richer than about 12.5 to 1 you give away power and fuel economy. If you have to go richer than that to prevent detonation you would be better off retaring the timing and running leaner.
YMMV.

Yeah, it's nice. Don't go under 12.5, you're just wasting fuel. Everyday driving? 14.7 of course (on trailing throttle), fuel shut-off on engine braking and 12.8 @ WOT.
