07 cm870 metering/timing actuators/soleniods

[Rawze]

Just some thoughts on it ...

If it does not have a boost gauge, then install one. CM8780's are notorious for boost issues as the turbo arm/ controller starts to get sticky on them. If the boost is falling off or acting up, that could explain the smoke, etc. A 530HP CM870 should be roughly about 37 - 38 psi (38 max) boost sustained under full 100% steady operating load, optimally.

Run the overhead valve adjustment on it and then do an injector leak test on it after its warmed up, and has acted up a bit.

Also, actuators can be checked as well:
