yes my concern is how much more advance? I'm already up about 5* in timing ( mid 40s now)...is it safe to hit 50* IGN? will that actually improve torque? I would be curious to see how the insight reacts when it switches to lean burn operation in terms of timing.
also my main question I guess is which will be the best air fuel ratio approximately for best fuel economy...is 17:1 good enough?
