    Where can I get a program and how much to tune OBD2 on these LS1's. I have a 2001 4.8 liter LS Silverado and I hulled out my cats and now have a code for the rear o2s. Sounds good now but sometimes i think it lost power.

    what are your plans for the truck? How far do you plan on tuning it? That would determine what works best for you and price.

    Well I just built the 4L60E tranny with the Zpac and the Beast sunshell, Corvette servos and flipped the acumulators. It hits pretty dang hard now, almost annoying. While I had the tranny out I hulled the converters. I know these LS1s just want to breath and figured it would help, but now I think it gets into limp mode sometimes because of the code for the O2 sensors. I plan on installing an STS turbo system with methanol injection. And maybe A small 125 shot of N.O.S.. I have a laptop mount built for the truck and am looking for a realtime program/ Emulator maybe to tune this setup. I have been trying to research the EFI live progaram. But cannot find many people that are running this program on LS1s, I know alot of people that are running this program on Duramax's. It is awesome and they are winning in the Truck pulls.

    I wonder if they have a forum for those trucks? ---Just thinking you might get some better info there.
