    Wrong injector data?

    Hey guys, got a bit of a mystery going on, I recently flashed to an 02 tahoe os for the flex fuel capabilities in my 1999 silverado on an 0411 pcm. I got that going and its cool and whatnot, but im having problems deciphering my injector data. They are # 12613412 part number injector, Which shows them to be 50lbs at 58 psi rail pressure. now the hard part is they are ls3 style injectors, which means the table dont quite match up. I retuned my ve and maf and im getting some ve numbers over 100% where there shouldnt be any. Ive used the ls3 to ls1 excel data sheet to get the data squared away by my numbers are still over 100% and the maf numbers are way higher than need be. Here is a copy of my tune, let me know if you need any logs. Im just trying to figure out whats going on here.

    You ever find any info on these? I am having similar issues. My VE is very high and my MAF table seems low. Additionally as I got to WOT injector pulse goes from 12ms to 22 from 80%tps to 100% TPS.

    This flat out floods the engine.

    I have tried two different base files (02 F-Body) with just importing the injector data and same thing
