67 twin turbo dart

Been dealing with a oil temp reading and gauge sweeper issue, but was out doing some pulls before it started to rain, was hoping it was going to be later but got caught in a good drizzle so that ended those pulls, but also to get the oil temp up and will check tomorrow if the sweeper goes back to base as it should. Have already re zeroed it per speed huts instructions, well second time time doing it since first time sensor was still connected bow this time was with it disconnected. Getting closer on the tune pulls, and yes 91 octane at only 5 psi, pulls to 4500 but leans out so I keep adding since I don't always have a co pilot to engage auto tune.

Just add like 10-15% above 4500 and see what it does. Is fuel psi stable above 4500?
