Default Ls swap+efi live and learning to tune?....

I've got an ls1 swapped into my truck. It's out of an 03 vette m6. All oem minus the exhaust and the air intake. I have efi live and have deleted vats, cags, and egr and emissions related stuff. I bought an mtx-l wideband and have it working on my efi live program. My question is, where do I start making a custom tune. How do I do it. I've read so many different things and am almost more confused now. Do I do the calc.ve or calc.maf thing or what. I totally need some help. The truck runs fine but would like to tune a little or at least learn for future swaps. Any help is greatly appreciated.

Since you're using EFI Live go to their forum, there is some very informative tuning threads there.

Try the Calc.VET procedure... it can be tailored depending on your goals

( be careful with terminology, this is not Calc.VE )
