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.
I've had more than one digital box go bad, I keep my standby 6AL to plug in just to check if its the digital box that failed.
When my digital went bad i had no spark at all, It's Really quite frustrating when the digital boxes go bad.
