It dosen't richen as you change SOI, EOI follows SOI as it advances and the difference between them is the PW (pulsewidth).
You can go earlier, I just didn't find more power on the stock LT1 engine. Careful though, go too far and you'll start to go leaner, you just won't be able to tell from a Wideband because the fuel will make it out of the engine on the exhaust stoke - still showing the same A/F ratio as the Wideband is an average measure of all air and fuel passing the sensor - not an actual measurement of what's in the combusion chamber during the power stroke.
