No. The only thing you are doing is wasting gas. 
I do not remember ever hearing that the VIN tells you if you have NGC or JTEC, only the PCM plugs being the deciding factor along with the separate TCM next to the passenger headlight on JTEC models.
Either way, you have to get the correct reluctor wheels for the cam and crank for your JTEC truck.
