r16 update on 07 still missing

[Smokey07]

I updated my tuner to the r16 and installed performance tune in truck and it is still missing. Does it bad at between 900-1100 rpms. Have tried other tunes and is still the same. Any info would be helpful.

I had something like that and also a hard miss start (sounded like it started on 3 then 4 then6 cylinders)....turned out to be the fuel filter..now all is good!

I just changed the fuel filter so i dont think it would be that. I took it for a short drive and truck didnt seem right. Seemed like it had injector going bad. When i set it back to stock it is fine. Also it seems like it does it worse when the truck gets up to normal operating temperature. Any ideas???

Mine was doing the samething so i just removed the programmer of the truck and will not put it bwack on till they fix these issues.i think it will kill thew injectors over time with this bad pulse threw ecm it could have something to do with my buddy loosing an injector after he put one on his truck just my two sense.
