Hello all,

I have a 5.3 with an LS6 intake and injectors on it running COS3 2bar MAFless, and its in an 04 Colorado. I copied over the values for the injector tables from a stock zO6 tune, and the truck runs like crap if I ease into the throttle its not bad, but if I do anymore than ease into it, it is somewhat jerky and lacks power something furious.

before I made the changes stated above, it had the factory truck Injector values in the tables and ran decent, but wasn't at full power. I don't have my WB installed yet, or a log for you guys, but it has to be something simple, right? I'm assuming its running too fat with the LS6 values, and might be a little lean with the truck values, especially at higher RPM beings it is only one value and referenced to vacuum on the truck intake.

Thanks,
Branden
