Did you return the fuel pressure to stock?

Did you get a programable 123, or the 1st version?

If you have V1, the only useful setting is for B20E/F, I'd use that on B18B & B20B's & then the curve is still too slow.

(The advance curves are designed for 1960's fuel quality.)

The only curves with vacuum advance are B18A & B20A, the rest have retard & the B18B had none at all.

I'm also wondering does the 123 D-Jet part work correctly? Putting the stock distributor back in 1st might have been the 1st thing to do to fix a D-Jet problem.

Also, 9.5:1 compression? I'm assuming you want to run on the lowest octane possible?

I'd like to see you get a dial indicator & degree wheel & verify that it is in fact a D cam & close to degreed in properly. Following the Greenbook method would be OK if you don't want to go to 'the hassle', BUT, the inlet system from the start of the manifold to the combustion chamber & the cam inlet duration & LSA are set in stone in the VE curve of the D-Jet box.
