Yes, you need them unless you're going to pay someone to do an open loop speed density tune for you.

Sorry for my stupidity but what is that monster? Speed Density tune? I had it re configured, is that different?
It is simpler to just use the 02 sensors and be happy with it.
OLSD means the PCM is going to control the fuel mixture at all times with no feedback from the oxygen sensor or mass air flow sensor. The OLSD tune is nowhere near as accurate as the live interface you get when using feedback from a good working set of 02 sensors. Changes in humidity and ambient temp will affect the tune. There are many variables that affect a tune and using the 02 sensors helps to compensate for the variances plus you normally end up with much better fuel mileage.

I really appreciate your input, I guess now, I am glad the O2 sensores are there. Thanks again.
