Just re calculated and got 0.1076. Thats using old one's at 30lb and new one's at 25lb for easy number's. Jayme will be more accurate.

With the new injector data and BPC set there's a fair chance the VE will need altering in most cells.

Better you than me in this weather! Post some logs and and a matching new bin when you're set up.

Just looked at the 2 logs you posted a couple of pages back. 109%DC and 1 AFR leaner than target so definitely needs an upgrade, do you think 24lb will be enough?
There's probably a formula to work it out. But as we seen earlier I'm no math's genius.

267 cc injectors should yield 488 hp with 12 injectors @ 80% duty cycle ,550 hp @ 90% dc
215 cc gives me 440hp @ 90% dc
theoretically the engine is 480 hp @6000 rpm and 570 hp @7200 but it will never see those revs
6400 rpm is the magic number 429 ft/lbs , 520 hp.
That is estimated with the Performance Trends engine analyser with accurate head flow and manifold flow numbers even weighed all components for an accurate result .
Thought the program might have been overstating the torque and hp figures but apparently not ,as I have had to up the injector rate.
Didn't want to go bigger as it might have caused dramas at lower ms opening times .
And then again I thought I wouln't max out 2 standard sets of 3.8l v6 injectors in a 5.4 l v12

yes but the v6 would never see 6400 rpm and they are at 70 dc bone stock. with good exhaust and intake they see 90 dc at 5k
