No, especially if they don't see it on there. I am not sure on the PCM tunes but you might have a problem if the dealer needs to reflash the PCM and it screws up your tune or just cancels it out.

What gets me is if my dealer does the tune or any other mod, the warranty is fine, but the mod is usually done half ass. Get it done by a specialist and it's no good. Isn't there something wrong with that picture?

They cant re flash it because most tuners lock the PCM But if you have any problems they can send you a stock one or you can keep your stock PCM.

So basically getting a tune on a brand new truck might not be worth the risk? I think I'm gonna do exhaust first. Me no like quiet truck!!
