Max HP and Torque from an ISX CM 2250 CPL 3917

[Mike in NC]

Thank you for your response. I am trying to get the owner to send me a picture of the data plate. The original calibration for this engine is CL10136. It was out of a KW and he installed it in a Pete. He said rear ratio is 2.64. The truck is a Wal-Mart spec Pete. I told him it could be fleet features or spec that is making it seem slow at low end. ESN is 79614517. It had some tinkering with it before he bought the engine. It is demandated. Not sure what all was done or who wrote the tune.

I have heard great things about you from a friend that passed away and I believe he had talked to you.

But thank you for your help!!!
