Can someone please help me get my car tuned or atlest driveable I can answer any questions it does run it's just sluggish and afrs are allover the place I can also post logs of me driving it when I'm home
 
Might be confusion over Speed Density and GM 3" MAF setting.
I think there is so if I have a gm intake sensor do I still use speed density table or no and do I have to turn off all SD inputs I had some trouble trying to figure out what pin outs to use for the gm and the aem 3.5 bar

Your ECU is seeing zero airflow reading. So your GM MAF is dead, unplugged, or wired wrong.
Could it be somthing in the pin outs cause i followed all steps during install maybe the sensor is bad I did get it for autozone
 
Heh. I see what's going on here. Steve got it right.

Go on the MAF Comp tab and change the drop-down menu "Base MAF Type:" to Speed Density. Then at the bottom right hit 'copy to ecu'.
Then do a new log for us to look at.
Sorry too hot Here in vegas to do any car work outside LOL but I'll get that log posted once this heatwave passes
