RE: CM871 Engine cycle... on a 2250, Boost above about 36 + psi or so and heavy torque would cause it too. They have a higher compression ratio than older engines and require less boost to produce the same power. If you are above 35-36 psi or so, I bet if you back off on the boost a little bit, it would go away. | |||
