I have a q-jet on Trans Am and Truck, it took me a lot of tinkering to get the q-jet on TA to start with just a flick of the key. The q-jet on truck is fighting me though and needs some more fine tuning, I just rebuilt q-jet so trying to stick with it for now. I might switch to a Holley on truck with vacuum secondaries and it should get about the same gas mileage as q-jet. In the end both carbs are good but q-jets a bit more fickle IMO.

A lot of tuning and lack of mileage is related to a slow timing curve. Especially at elevation.
What's your timing like truckin?
