I just got EFI live and want to tune my 2010 L99 Camaro Automatic. Right now im not worried about the 6L80E. I have a few engine mods. I have a American Racing Headers 1-7/8 Long Tubes with Full exhaust and muffler delete, A K&N Air Intake Kit. I just installed an Innovative LC-2 Wideband and have it also hooked up to a serial port for Scan Tune V7.5 for EFiLive.

I Printed out the Swingtans VVE Dial Guide for E38 ECU, I set the engine in open loop, and confirmed it is.

What are the next steps into tuning this? I seen and heard about a BEN factor but not sure what it involves.
in that manual it says too unhook the yellow wire in the MAF sensor harness....Do I do this too? The guide shows its for an L76 not an L99.
