Sounds like here's the breakdown:
- SOI in the 370's
- EOI in the 120's
- Pulse width over 6ms
- Rail pressure tapped out at 3000 or so

With those conditions, I think the only thing left you can do in the tune is lean out the mixture, right? (or reduce the E content as noted) I don't see where you have any other options within the calibration.

Side note- I think it's great that we have guys like Jason and Joe on here that contribute on a regular basis, with lots of first-hand experience on these platforms. Really helpful for guys like me who tune a small handful of cars for myself and close friends as a hobby, who don't have the week-in, week-out experience these guys do.

So thanks to both of you (and a couple others). I'm glad you guys are here and willing to contribute.

Currently I command .83 at WOT. The only thing left to do is tinker with some more of the fueling system options and if I wanted to lose some power up top, either lean it out or reduce the e content and mix. Either that or spend $2000+ for a set of 30 over injectors. Regardless, this is all good stuff that should be despite physical mods to get the most out of the fuel system anyway. Because the cam is LT1/5 based I noticed it tends to run harder and more optimized either borrowing the ZR1 tables that I have from the base tune file, or running a blend between my ZL and ZR tables.A lot of tables have been modified from the original base ZL1 tune file.
