You might want to get some bigger injectors - these are pretty much maxing - all ready hitting 90some percent duty cycle. Your MAF could use some work - Probably need to add 4% from 5000 and less hz cells and clean it up a bit more up top unless your commanding different air fuel ratios? - Air Fuel goes from low 11's to just over 12 - could be due to your injectors maxing too? Looks like the timing for your setup is almost spot on...
Just my observations...
2010 Vette Stock Bottom LS3 - LS2 APS Twin Turbo Kit, Trick Flow Heads and Custom Cam - 12psi - 714rwhp and 820rwtq / 100hp Nitrous Shot starting at 3000 rpms - 948rwhp and 1044rwtq still on 93
2011 Vette Cam Only Internal Mod in stock LS3 -- YSI @ 18psi - 811rwhp on 93 / 926rwhp on E60 & 1008rwhp with a 50 shot of nitrous all through a 6L80

Yea i agree on the injector part my next mods will include them. How do u determine the maf being 4% low below 5000hz? And no im not personally commanding different afr. What is the standard afr variation under wot? I appreciate the help. edit lol the 4% to fix the ltft's before wot duh...correct?

YesSame thing to fix the changing a/f ratios during wot too
You'll also want to keep the MAF curve as smooth as possible... AND add as much data to look at in your logs as possible - you can never have too much info - might help you out if you run into some odd ball problem...
