Beyond jetting, since you'd presumably want to get it to have ok part throttle economy - instead of going up too many jet sizes, you can also downsize the air correctors. This will make it go richer up top a flow increases. Normally this would be way too rich on a non boosted car, but for turbocharging or supercharging, you actually want it to go richer up top, richer than it needs as far as fuel to burn, as some of that fuel acts to cool the intake charge a little bit further. So reducing the air correctors can do wonders. Don't go ridiculous, 1-2 steps smaller on the secondary, and 1 on the primary to start with and see what that nets you.
