Dyno results - Tquad vs Holley vs Qjet - tuning issue, too rich

I’ll state that my time with there use (replacement units) was really good and trouble free. Having them on a 360 & 400, the small primary was a little restrictive on the 400. It was fine in the 360. Both were mostly stock (AKA - No cam change) engines with bolt on parts. The electric choke was a great item to have on them. One wire and done.

Do the 1000s with the single booster have a longer booster? In other words, is it different than the production 850 double booster with the outer ring removed?
