I like it on our car with the Qjet. When we were running the 4GC and Holley carb combinations it was never a problem with our old fuel system. We found those two carbs are more forgiving. The Qjet was harder to get consistent performance prior to adding the Product Engineering bypass. Everyone has their own approach to make their car work and opinions are going to vary on where to spend their money.

Holleys are easier to change the boosters on. Just a thought.
