Sounds like you don't have enough fuel due to a delivery issue. Did you upgrade your LP?

yes, you are draining the rail. if you install a rail gauge, you will see the pressure drop significantly and then the popping starts.
the popping really isnt a good thing. for the injectors to atomize and spray the fuel in a good pattern they need the pressure that they were designed to run.
low pressure results in a poor pattern and egt's will get pretty high.

A big line kit or an upgraded CP3 with an auxillary lift pump should help your fueling needs.

Several things cause it,..

Primarily it will be too much timing for your setup. Also excessive pressure from a pressure box will cause it. Those are the two primary contributors.

Get the walbro 392 and big line kit from glacier diesel power. Dont forget a fuel pressure gauge and like they said, a rail pressure gauge would tell you what kind of pressure your running in there.

Is surging also a sign of CP3 short of fuel? A LP and a Big Line kit are my next mods.
