You can get away with deleting the rear O2's but I believe you will need the front O2's....... I know that even if you don't run thr rear O2's and do not modify the ecm, it will run rich...... So I could only imagine if you run none at all......

Are you runing truck or car EFI manifold?

But, he'll get better MPG with the 02's/MAF closed loop.
I think he just needs to get the correct tune and that will fix the problem. IE a SD tune.

ok.. im going to sd tune and see what happens, we only have unleaded fuel here, we have 95 octane and 98 ocatne only,leaded fuel is no longer legal here, i thought we have one of the best fuels in the world....... i live in dubai... maybe other countries here use leaded fuel.... i guess
