Anyone run the Weber knock off 38 progressive 2bl here on their 225?

Recently bought a Weber 38 dges knockoff from Amazon and it claims on the box to be a 390cfm carburetor. When I bought it last month, $110 shipped. Bolted on to a Clifford intake. I feel that the main jetting is perfect for a 225 right out of the box, but the idle jets need to be larger. I do also have a the Clifford header and true dual 2.25 exhaust. I have a slight hesitation off of idle, but I believe upping the idle jets will clear that up. I've not pulled plugs to see how it's running, but daily driving with a 40 mile commute has seen zero problems and it's been about 2500 miles since installing. I did also have to bump the timing up too. I have seen that you can take parts from the 32/36 and make the 38 progressive, but I don't think it would flow enough on the single barrel to be worth it. Would probably be worse than the original 1bbl.
