I can't seem to figure out why I'm only seeing a max DYNCYLAIR_DMA value of about 0.50 grams/cyl. Any ideas?

Custom OS 3, 2003 Corvette 4L60E calibration.

After putting the pedal to the floor and a downshift (4L60E), I see the following values:
- RPM: 2750
- Throttle: 98%
- DYNCYLAIR_DMA: 0.50 grams/cyl
- MAP: 97 kPa
