Bad crank position sensor? HP tuners scan attached!

What do you guys think? I'm having problems with it idling very rough once it warms up. Watch the 'current cylinder firing' tab and notice that a lot of the cylinders do not show up. I have it set to a high frame rate so you can slow it down and watch it closely. I know sensors do not like heat, and since the crank pos. sensor is right by the turbo mani, I could see this being a likely problem.

It is also extremely slow. I ran a 14.5 in the 1/4 mile w/ my current set up!

I attached the scan and config files

The correct firing order for my engine should be 1-8-7-2-6-5-4-3

the first length of numbers from this scan show

6-7-2-4-6-0-2-5-7-1-3-5-7-1-4-6-0-3-5 and on. It seems to be just random
