Shakedown passes dialing the thing in on 19psi with my 7665. Footbraking the car to a 1.52 60', 4.26 330', firstname.lastname@example.org. I let off because it was getting dangerously lean due to a fuel pump failure. Setup is stock 302 shortblock, ported gt40's, e cam, 1.7 rockers, speedmaster 4150 efi intake, 75mm tb, 7665 on3 turbo, c4 with a way too loose converter (#7 pump and 082 stator), 3.08 gear, on a 275 pro tire, e85 fuel. I felt a 6.40 pass coming, but had to abort right around 500 feet out. Leaving on 4psi, 2600rpm 2-step, 19psi total, 11.0 afr, and 13.5 degrees.
I totally forgot I had posted this. I wasnt, the pump was fine on initial tuning, but I hadn't made a full 1-D pull after I dailed in my VE table. I had just used 2nd gear for tuning. I made a few changes over the winter along with replacing the junk pump, hoping for some positive results.
