Sounds like you have it dialed in! On the data logs running the 109, does it pull timing on occasion? Or, did you go easy on it in the tables? What is your race weight?
I watched the vid and seen you run at Famoso. At that elevation, you're FCR is around 22.5/1
Laynlo- You're under 1k too. According to the chart, you were around 24.5/1 at the time of the "accident" LOL
Do you have any pics of the dead slugs and cylinders? I'd like to compare them to the ones in another thread.
Here is the chart I am using if anyone is curious.

It has formulas for corrected CR as well as FCR. The corrected ratio should be 100% accurate. The boosted ratio is probably not so much since, like everyone was saying, the same blower and pulley setup can yield different psi.
Also, for those blending fuels, here is a cool octane calculator. Plug in the gallon price and it will calculate how much a tank of gas costs too!

* It will not work with alcohol blends. According to Sunoco, gas/alcohol blends aren't linear.
