GM Performance Parts harness? Who has used one and thoughts on it as compared to the other brands? Maybe a price comparison? Gotta get one soon. I don't have the factory harness and the combo is Ls1 with 4l60e. Thanks.

Unfortunately there is no GMPP harness yet that will run an LS1. Plus the GMPP harness/controllers wont run an auto. You need a seperate trans controller kit for the auto.

Rumors of one but, I guess it never really happened. Thanks for the reply, I'll move on to other vendors.

+1. GM does have some crap to deal with right now. They have bigger fish to catch, like everything in the "hard parts" bin which is phenomenal parts wise. The last thing they're worried about is a bunch of wires in a box! LOL.
If you are looking for a complete controller setup try Mast Motorsports. I know they were working on a LS1 setup. I use their harness and ECU on my L92 and I was very impressed with their products and their support.
