What or who makes the digital sync tool for the gen 2s.?? It was all over the star vmax site, but since it's now been abandoned, and I can't remember what it was called. I have 2 (round Gage style, and the long tall black one with the silver weights) but I can't get them close to each other no matter how much I turn the screws. It runs good, starts, idles get great gas mileage I've been getting right at or just over 100 miles before the low fuel light comes on. I just want to get these TBs readings closer.
