Dyno results - Tquad vs Holley vs Qjet - tuning issue, too rich
Sorry,
Have to disagree about blocking the bypass holes. They probably did lean out the mixture at small throttle openings. But blocking them off will mean that the blades are open further at idle, upsetting the delicate transfer slot position at idle. Some combos may benefit from blocking them off, but saying as a blanket statement that they should be blocked off is incorrect.
