new ls6 with custom ls1 tune?

[DemonSpeed]

Im in the process of switching my ls1 to an ls6. I have a custom tune via a predator right now (runs a little rich). My question is how will this affect the new ls6? Id like to contact James to get a new tune but the GM tuning site isnt working. I need the custom tune because I have deleted Cats so I cant go back to factory tune. My current mods besides the ls6 upgrade are: Whisper lid, slp cold air, Hooker long tube headers, 3" true duals w/o cats, TCI street fighter 3000 stall, 3.73 gears. What do you guys think?

Mail order tuning or, if you are close enough in VA, tuning on the dyno will get you squared away. There are link to mail order tunes in the services section of my website (see signature). Those are excellent mods and the car should work very with them.
