So generally the stock injector's limits are 350 I think I heard on stock compression?

Thats a guy I know with stock injectors and it looks like he's running horribly lean at just the 300 mark.

What fuel pump is he using?

That graph doesn't look too good, and I really doubt his injectors are causing that lean-ness. ...Whats his tuning device?

He hit 17:1 a/f ratio at full boost?? :ohnoes:

I think you should suggest he do a compression test on that motor.

Thats not injectors, thats probably a fuel pump, clogged fuel filter, or fuel dampener bypass causing an issue, or another problem... for that one dynograph, I can link you to 2 instances where people made over 400whp on stock injectors and compression while running 10.5:1 A/F across the board
