Cylinder Airmass drops to 0 while driving

I am working on an Procharged 09 Saab Aero. While I am driving the CylAirmass will suddenly drop to 0 which makes the time jump, inj msec go to min, etc. This obviously causes a stumble for a split second. I cannot figure out why this is happening. We are running in SD on a 3 bar map.

Any ideas?

In the log file it is near the end at frame 21375

You've got your MAF dtc's set to no error reported - will cause false rev limiters and all sorts of issues. Even in SD operating system the MAF is still looked at. Zero out MAF scale then set DTC's for MAF to 1st error no ses.

Thank you I will give that a try. I wonder if that has anything to do with the crazy torque management retard I have having.
