No, FCA wanted to make sure 2.0 sells better...by loading garbage tune/calibration on v6 ECU.I agree completely that tuning can help the 3.6. The problem is the factory and any extended warranty is toast at that point if you have engine issues (because of course FCA will blame everything on the tune. It's a slam dunk denial for them).
I am curious if there is extra HP/TQ readily available, why doesn't FCA send it out of the factory like that. You would think Jeep would want to be able to advertise the best possible numbers for its engines. I have to assume its either some kind of weird politics, such as needing sportier products like the Chargers/Challengers have more power OR maybe the engineers concluded the engine will not be reliable enough long term if they pushed the power envelope.
