seriously i wouldn't worry about it on an LT1. it's just not a precise machine.

even injector voltage offsets, if you don't have them, are no big deal. unless your alternator shits the bed it only ever uses two cells of that table anyway. just rough in the injector constant and throw the offsets in if you have them.

it's like obsessing over tuning the far top right corner of your VE table, which unless you have a standard transmission and floor it from a standstill in 6th gear, you absolutely can't reach, and even if you did, fueling accuracy in that region doesn't matter.

in most of my tuning i never touched that and they were dead on accurate with no hiccups in drivability

focus on things that make a difference. kur4o's EOIT stuff probably makes way more of a difference than all this
