Anyone tuned a LY7 (Acadia, Outlook, CTS, G6)

[duramax2500hd]

After tuning only my 2005 LLY Duramax, I still have a VIN license left and my wife's 2008 Acadia is my next candidate. Don't know how much I can get out of it, but I don't see where anyone has really tackled this motor. It seems like a stout V6 and there may not be much to improve on.

Anyone have any experience with this motor?

Would like to know the same thing.

install a wideband and do a run with it... that way you will know how far off it will be...

What do you want to improve on??? efficiency?

Don't have a wideband... would like to improve on efficiency though... I've tried driving it responsibly, but the mileage just isn't living up to the claims.
