Can't get enough fuel!
Alright guys I am in the middle of the AutoVE tuning process and it seems like I have hit a wall. I have put the PCM into OL and I have a LC-1 WB hooked up with no flashing LED light, so it should be getting the correct information. Where I am having the problem is with the BEN factor. No matter how much I multiply the VE table, I continue to have logs like the ones attached. Below are my mods:
2000 Silverado with 6.0L, 42# injectors, Whipple at about 6si, K&N FIPK filter.
What should I do to get the BEN factor down if changing the VE table does not make it come down? Should I be getting above 200% in the VE table? I notice in a lot of other tunes, the VE never goes much above 100. Any help would be appreciated.

I don't think that your IFR is set correctly. Are your injectors 42 lb/hr at 4 bar. I think that they are or even 44# if they are the Racetronix injectors. I worked mine out to be:
43.82 lb/hr * .12599778 (conversion factor) = 5.5212 g/sec
or 42 lb/hr * .12599778 = 5.2919 g/sec
Your IFR Table {B4001} is currently 3.7734 g/sec in all cells. You should set it to 5.5212 in all cells and flash the tune. You may need to adjust your Main VE Table {B0101} because it will now be off. Then Auto VE again.
Your PE is not set up properly either when you go back to CL. It is 1.00 Lambda in all cells and should be scaled to work its way down to 0.78 Lambda (11.5 AFR) above about 2500 rpm and your entry to PE Parameters need to be adjusted (MAP and TP )to how the boost comes in with the Whipple.
Since you are not running a COS:
YOU MUST BE CAREFUL IF YOU GO INTO BOOST THAT YOU DO NOT GO LEAN AND DAMAGE YOUR ENGINE.
Because the PCM will not know you are in boost and PE is not active in OL AFAIK.
I think you need someone to review your tune before you do any more Auto VE tuning or driving in boost and make sure it is safe for boost because it does not look safe to me.

I have tried increasing my IFR and anything above where it is currently set and the truck just dies when I try to start it. I will give it another shot though because now that you mention it, I think that was because I had an intake leak.
