·Ok, went out and dynoed the "big twins" again tonight:
21.5 psi, or what I run on pump gas on the street: 698/551
28 psi, or my hold-onto-your-balls setting: 780/625
I could use some thought on the following problem: I didn't spray it tonight, as I was getting baselines for all turbo. A/F held pretty close to 12:1 on the low boost, but the high boost caused a steady lean-out towards redline, as high as 13:1 on some. EGTs were fine, of course - it was just a one gear pull. Normally, this is a standard indicator of lack of injector, except that I am running 850s. Fuel pressure is at the 43 psi static standard, and I am getting a perfect 1:1 rise. It's almost like I am beyond the map sensor reading capability, but I'm not of course. Ideas?
