71 Duster 360 turbo build

Ok I had to go back and edit that post but I’m with ya now. 1000 rpm doesn't seem like enough drop. You could be driving through the converter, slightly. Looking at your log there is a distinct 1-2 and 2-3 shift though. I’d focus on getting the voltage situation figured out, then the fuel situation, and then do some math to figure how much slip it has.
