O3 Hummer

[teddyls1]

A friend of mine has a 03 Hummer and he just put a Procharger kit on it. He wants to use my efi live to delete the rear O2. Can we do this if the tune that Procharger sent him was not done with efi live.

If you can successfully read his ECM then you should be able to flash to it any changes you make.
