X15 questions

[Running rough]

That’s what I tell my guys x15 is still seem mid stop liner design, I don’t recommend running under 1500 rpm if you have 1850 torque and above and are hauling heavy, they do seem to slightly have more compression ratio then cm2350 isx15/cm2250 isx15, I was told cam profile is different along with pistons and injectors, I’m talking about performance series here, one thing for sure, I can’t see them living those liners I mean if you run stock timing and do the off-road demandate, the combustion recipe is a LOT Different with egr to calm it down, pure air is a lot more volitle then egr/air mix, and with these newer higher compression higher egr flow engines it’s a delicate subject to do, doable yes I think for sure but it takes testing and trials
