Looking at the 6.2 liter truck tune files I have, I'd say your stock injectors are roughly 50# at 58 psi. Get yourself some good injectors and pulley that thing down!

 

I actually bought this setup off the OP for my dad for a 2011 6.2 NHT 4x4 truck. We ran it on stock injectors at first but it was going lean above 5k on stock injectors. Had trouble with the autocal with the injectors that came with the kit, so decided to go all in and bought ID1000s. Runs great now. I still don't have a boost gauge hooked up, only an AFR gauge(single door pod gauge setup for stealth). But the tune is spot on for AFR 11-11.5 all the way to redline and should have enough injector (but probably not pump) to run e85.

 

I didn't know OP got a ZL1, when did that happen? Has he abandoned PT.net for the auto forums?

Was he ditching the blower to sell/trade in the truck, or do you not know?

 

I think he was returning it to stock to sell or trade in, presumably for the ZL1.

 

Damn.

 

after getting back from my dyno tune the oem stock injectors are at 98% not 84
