Looking to upload the right ecm for EFI Live tuning on a 08 Chevy Silverado 2500hd with the 6.0L motor and 6 speed Tranny...

I think that its:

Gen IV LS2 E40 ESM.... Is this right?

Thanks in advance...

Can someone point me to the newbie intro forum??? I know I know... I hate to have this as my first thread!

But I will intro myself soon enough!
