The initial advance is set at 10 degrees. The red line is with the initial advance set to 3 degrees, bumping the whole table by 7, right? The green is with the initial set at 7 bumping the whole chart by three. I ran the van with 0 initial and lost power over the other two. I ran the initial advance at 10 and the power was about 5 hp lower through the whole range. The run in pink was with altitude correction turned on with the same settings as the green run. I let off there was no use pushing that combo. The lack of the torque converter bump is because the chip is locked into 3rd very early and the converter locked to allow a lower RPM pull with good repeatability. I think there is a little more in it with a more refined fuel and spark table, but really I dont see where it's going to gain another 30hp staying below 4500 rpm.
After a few tweaks the fuel stayed pretty steady for wot at 13 plus or minus a little.
Here is what was started with pretty much the same temp conditions last year. All numbers are corrected for air and humidity anyway.
