searched and searched old injector post but still need help
 

I'VE been researching if I need injectors for no more that 6psi on ly6 6.0L people are saying I do but they have like 2000-2004 lq4 trucks mine is 2007.5 LY6 and I've read the older 6.0L have like 32lb ers stock and mine has 40 lb at 58psi am I wrong? And dont most turbo kits have 42lb.ers as an upgrade. So is there a reason for upgraded injectors? Ifso I still need fuel wouldn't a boost a pump be enough and much simpler and "CHEAPER" solution. I'm just looking for a educated answer with experience with the newer ly6 6.0L motors

did you ever figure this out? Im trying to boost an 08 LY6 and help woulb be great thanks

I Cant remember but i wanna say i was on the verge of maxing out the 43# 8.1 marine injectors on my stock LQ4 with 6 or 8 psi. If your staying stock with just a little boost, id say your good but a cam or something to add more airflow, your prolly gonna need bigger injectors.

If you had a boost controller you Could adjust the boost till your on the verge of max? Just thinkin out loud.
