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

They have those. I noticed them but was unsure of their function. On the 2nd Tquad which has the enlarged venturi but still has the 2 boosters, idle, low-speed, and the transition between works very well, just as good as stock. I'm wondering if playing with those would be better when the car is driveable?

Pulls were started at 3200 rpm.

If you run it with and without blocking those holes you might see a difference in when the primary booster begins flowing.
