71 Duster 360 turbo build

Thank for pointing out the voltage drop; I had not noticed that. I believe I need to run a bigger power supply wire to my microsquirt fuse box which also supports the coils. The fuel pumps are powered right off the battery so I doubt they experienced the same voltage drop.

TPS was recalibrated after installing the new injectors. I’ll do it again with a bit more foot pressure.

The fuel pressure drop and lean spike was scary to see afterwards. I was too low on fuel and when the tires broke loose it must have uncovered the sump. I’m glad the motor survived. New fuel sender arrives today.
What amp alternator are you running?
