Like Tight said, when I special order...I don't plan on doing on doing engine mods till after the warranty is up...

I would wait and see what ford has to offer for the 2013 before ordering at 2012. I think its going to be released next month sometime.

I totally agree. I'm going to wait a year or 2 until these tuners get this stuff ironed out. I've got a 2012 that I picked up back in July. I special ordered it. I'm the only person that's ever drove it on the street since it left the train lol. I want a tune so bad though. I really want to tweak the throttle response.

Has anyone ran into these issues with a ProCal tune?

That dealer is going to do everything they can to void that warranty. Did you see that Ford memo from a couple of months ago regarding aftermarket parts and tunes? Magnusen-Moss act or not...

BTW it does not matter if you return your tune to stock or not.
The dealerships can see if an aftermarket tune was put on these new 5.0's even if they are returned to stock.

Right now there is more of a risk when it comes to modding these cars than the other Mustangs. Seems more problems are happening and Ford is REALLY cracking down on voiding warranties on these 5.0's when mods have been done and something goes wrong. Ford even put out a letter to the public concerning this.

Something to really think about in my opinion if you buy one of these and
want to mod it. Especially until they have been out a while and the kinks are worked out with them in the next year model or so.
