OK, Correct me if I am in the wrong forum.

I have a 2008 Denali and want to buy EFI Live so I can tune it for the mods that have been done. Can someone steer me in what I need to buy to tune this truck. I have LT's with full exhaust. No cats. Vera-ram intake. Msd wires. I am pretty sure it is running lean and I want to get rid of the nose dive shifting from 1st to 2nd and 2nd to 3rd. Can I do these things with EFI?

Thanks for the help and I am glad to be a member. I hope to learn alot from this site.
