Tuned or not?

Hey all,

My dad is convinced that my truck has been tuned and that's the source of my problems is the tune is bad and it's throwing the PCM off...

I'm convinced that my truck is stock tuned and its a bad injector.

My question is, is there a way for someone to have tuned it and left it? How would/could I tell?

Have the dealer flash the PCM. A tune wouldn't confuse the PCM, as it would change the PCM tune. If you have a chip, that would be different. You can tell if you have a chip, because it would be mounted on the PCM.

whats the truck doing?
if its a bad injectors pull the valve covers off and let her run and if an injector is using lots of oil compared to the others theirs your bad one.
if its making a cackling sound its prob the number 8 long lead injector being noisy.
