That sounds to me like what those idiots who hang out on the engine tuning/delete sites would say... because none of them seem to have any clue how to do anything past unplugging crap and making codes dissapear form the dash, then wonder why the engine blows up prematurely. .. or like you said,... runs like crap after such complete half-arssed garbage.

As far as just generalizing goes ...

Not sure about "worse" .. but there are added features that are not in the CM2350-X15's.. like an added "Predictive road speed Control", "Predictive engine braking", some kind of "Predictive Gear Shift Manager", some new "Passive de-soot assist", some stupid "On-Ramp extra boost" that does more harm than good to the engine at low RPM, and a few other added ramp-rate and attempted "fuel savings" limiters that try to limit how you drive the engine in various ways.

Here is a list of some of the others that are also in these newer engines..
