71 Duster 360 turbo build

Transmission is in. Took it for a drive and everything seems to be working fine. Stalled the new converter up to 3500, and it may go a bit higher, but the engine is bogging hard. With no changes to the tune it’s running pig rich under boost; under 10:1. Double checked the fuel pressure, and verified it’s rising slightly less than 1:1. Normal driving AFR’s are still exactly where I left them. I’m hopeful that the new fuel system really is that much better so I can up the boost a bit more! Tomorrow is probably the last cool track night of the year so I’m thinking about going if I can get the tune dialed in time.
