2ndgen,
Call Edge, tell 'em you wanna upgrade, but that your truck runs like crap w/o their Comp on there (not enough timing or fuel) and so you'd appreciate it if they'd send you a new Drag Comp w/ a return label for the old one. That's what they did for me... but my old Comp was fried, not in working order at all.
Good people to work with... cost $125 to upgrade to the Drag version. I believe I talked to James when I called last, but not 100% on that.
