Noticed that the cold start with 2.5 bar fuel pressure regulator the engine acted like not enough fuel for cold enrichment, but ran fine after warm up. So I tried a 3.8 bar (55 psi) FPR from a Turbo Dodge. Engine seems to like the 4-hole injectors at the higher fuel pressure. AMM adjustment was still within adjustment range.

Found some specs for the Supercharged Buick V6 white top injectors @ 3 bar:

308 cc/min @ 3 bar


346.33 cc/min or 32.05 lbs/hr @ 3.8 bar

These 3.8 bar specs are about equal to the 0 280 150 804 (B230FT w/ LH 2.4) injectors at 3 bar.
Trying to understand stupid people is like trying to pick up a turd by the clean end.
