Still fighting my issue I added the shielded trigger wire, did distributor mod and changed tach but still missing and having the shifter change gears to soon (elite rpm switch from digital display). Going to try replacing the digital 6 box with 6al that I ran trouble free last year and see if problem fixes itself.
I added nitrous this year and wanted the digital box to pull timing when spraying, only reason I changed from 6al box.
Double check your settings on the digital 6 box.
I'm sure you got one or more of the dials wrong.
Make sure you are absolutely sure you have the dial on 8 cylinder setting.
It can be confusing.
I bet the box is set wrong.
Also check your high speed rev limit on the dial.
