Front O2 and MAF Delete? Hey guys, I have a twin turbo LM7 that is going into my drag pickup. I am finishing up the wiring and forgot to weld in bungs for the front O2 sensors. This car is only going to be used on the drag strip where it will be run wide open so driveability is not an issue, as I know the front O2 sensors’s job is to help trim fuel along with input from the MAF. Which brings me to my other question. If I do not already have my MAF, nor do I have the bungs for the front O2 sensors, would it be better to get rid of them both and go with a Speed Density tune? And if I went that route, do I need to do anything with the 3 extra pigtails (DS O2, PS O2, MAF) or will they be okay receiving no voltage signal? I am going to be using a wideband after each turbo to be data-logging my AFRs on the track, so I don’t see why the fronts would be needed.
Thoughts?

It is never going to see any time on the street. 100% 1/8 mile track only. I have heard a few people saying it won’t correct for things like air temp or pressure without the sensors, but I was planning on just making adjustments based on data logging at the track. Are there any foreseeable troubles doing it this way?
