I noticed when data logging fuel rail pressure (actual and desired) at certain points the pressure reading jumps from 18000 psi to ~62000. This matches the corresponding desired fuel pressue. If I'm not mistaken the max for the Duramax is around 23000-24000 psi. All of this occurs when accelerating. Anybody have any ideas? It is possible I am doing something incorrectly since I am still learning / playing. This is on a stock tune.
