Anybody have any ideas why the pulse width is bouncing all around like that when the rail pressure is holding as desired?

Tune was set up to fuel 1950 us at 180-190mpa.

Made some changes and it went down the track tonight holding pulse steady! Guess I made the right changes. It may have been the torque table in the tcm but I'm not 100% sure.
