No problem, I haven't seen that behavior before in a log so it was interesting. I took a look at a longer log of mine and at that time scale my fuel rail pressure appears to follow commanded almost exactly. I do have the little spike as it ramps up and hits target pressure, example: ~1020 in your log so I would call that little anomaly normal behavior.

Right on, we're gonna try some different pump settings first before I tear into it. Tuner thinks the lowside may be too high and the highside has no where to go when I let off, causing the slow ramp down. Gonna run the new settings this weekend and see if their is any change, your insight has been great and now I know what I should be looking for when I come off the throttle. I guess at least too much is better than not enough
