MSD coils

Well,, as I posted in the SharaDon section. We have a new best of 11.29 @ 116.

What was the reason??? Good air ? 51* 1100 ft DA. The extra 2lbs of boost??
Were we having problems with the old spark plugs. Without knowing it????

Now the truck coils are a bit different then the car. But??

Would 2lbs of boost and better air account for a .45 and 7mph change in et on a 5100lb truck?? I don't think so.
