Bad maf or o2 sensor?

[cantgo2fast]

So after doing a HG and doing a few other upgrades went to start the car. car started right up with the mas unplugged but ran like poop. Some changes i've made: 1G CAS, wired in the wideband simulation from my o2, 274 degree cams, and vacuum lines eliminated via the taboo diagram.

Since i converted to a 1G CAS i set the base timing, its not quite perfect becasue it wasnt totally up to temp but should be good for idling/free revving. With the mas unplugged it runs pretty well, the cams make it a little rough but i haven't degreed them at all. I can free rev it and its fine

With the MAS plugged in however i have to give it gas for it to stay idling. I did get an IAT code from the computer. The only other thing I could think it could be is that my downpipe isnt fully connected because the flanges are off slightly so the wideband is reading really lean. Im hoping someone can look at the logs and tell me easily. Since my hard drive died on my last computer i have nothing to compare it to in terms of airflow and injector duty.

Im not sure if logs uploaded correctly so let me know.

would you please install V3 Software to your laptop? i think most people are trying to help are using V3 software.

I will try to make some new logs tonight. stay tuned

On my last log today I was getting -71* as an IAT value, isnt that a symptom of a bad maf?

Here are the new logs. IAT looked normal and the MAF itself physically looks fine. It smells really lean so im guessing I jut need to get the exhaust buttoned up before continuing. I would till like to see my data compared to someone who has a working car

The log with the maf plugged in has considerably higher timing, the non maf idle actually has negative timing??

Any thoughts on what could cause this? I still cant tell if its the fuel or timing that's my issue
