Turbort,
I agree the crank trigger is the last ditch effort - but in my case I replaced everything possible in my ignition makeup, short of going into the motor, and nothing helped it. Even despite the motor being just put together last year, there still had to be slop in everything just enough to cause the problem. Craig when I spoke with him said that this is NOT at all uncommon, and actually more common than people care to know. I think his figures were 99% of all cars making good power see (actually don't see it cause of the lack of logging capabilities) this happening.
I was given some good advice long ago by a fella that I use everyday and had given me the opportunity to develope some terrific ideas at work and in my racing.
"Don't try to control things that you will never control. If you can bypass the actually problem at hand, and make it work another way, then do it."
Its sorta the thinking outside the box theory.
But at any rate, I do understand that all other possibilities need to be exhausted and he should explore those first, like I did with changing the ignition components first.
I would bet that Craig might be able to offer some insight into what the problem might be he is seeing. Try giving them a call at the number earlier in the post. They are not easy to reach all the time, but very helpful when you do get them on the phone!
