So, this is my first post. So please bare with me, and sorry if I sound so new to this. I have a 97 k2500 suburban with the 7.4 liter engine in it. I have only started to do some mods to it. But nothing major yet. I have done the 0411 swap, K&N CAI, and have changed out the fuel pressure regulator and injectors to ones that I was told match stock injectors.
But I do not know where to start with the tuning of this beast. It does start and drives ok. Seems to me little there is a lose of power from the black box that was in it, and it seems to run a little rich. I have included a file from my first test log after installing the 0411. Being that I am new to this I am not sure exactly what I am looking for. But to me the 02 readings are all over the place and the Advance seems really high to me.
Can anyone point me in the right direction? Any help would be greatly helpful. Good thing is that I do not drive this truck very often, so it is not a major rush.... Just want it to be like it was before.
