I have never attempted a COS before I have read the tutorial millions of time now and feel comfortable to do it to my truck. Although I was looking more into the COS5 for the Nitrous controls. Here is what I found:

My OS 12202088
My choices are 012500xx (either 01,02,03)

I was reading another thread here in which I think he flashed in another OS (12225074) then ran 01290005. I am looking for more information on this please.

I also noticed a lot of talk about tps ve table I wish not to use this I take it this is something that can be enabled and dissabled. Is this a varient of Alpha N tuning?
