I just ordered tunes from VMP, so I hope his tunes will not have the same issue. Is the timing normally adjusted with custom tunes or do I have to specifically tell Justin about it?

Aftermarket CAI's, can play havoc on these trucks w/ stock tune. VMP will adjust his tunes for the CAI, and you should be squared away, and with out issue after you upload the new tunes.
I have K&N CAI, and VMP tunes... Love them and Im w/o Issues!
VMP ROcks!
