The last time we had it out the car ran it's best run to date. 2.149 60ft, 9.638 @ 71.55 1/8th, 15.085 @ 89.88 1/4.
The air was about 200ft. better yesterday and by noon the wind wasn't a factor. With the new header in place, we started with the factory tune back in it as to try and not hurt anything. After sneaking up on it all day it finally went 2.133 60ft., 9.594 @ 71.63 1/8th, 15.055 @89.43 1/4.
So it picked up ........nothing......
It does seem to be falling off after the 1/8th and the numbers support that. It wants a few degrees less timing and about 5% more fuel with the header.
Back to the drawing board!
Doug, drawing boards are what designers used to use before lap-tops.

OBTW, anybody with any comments/advice, please feel free.
