My friend, before you start questioning my statements, please search around and find out exactly what goes into creating a tune, none the less a tune that works perfectly with thousands of the same vehicle safely and effectively. You can believe what you like, and your right about the marketing standpoint, but you are greatly mistaken if you believe its all a scam and can get it done so quickly.
The reason you see Ford and Chevy tunes out within a year is because companies used to be mainly focused on Ford and Chevy and lesser on Dodge as it wasn't such a performance market minus the specialized companies for Mopar. These companies put major man power into motors and tunes that are MUCH easier to tune (no thanks to Chrysler on that fact). Up until the release of the HEMI's and SRT-4's (and so on), there wasn't too much out there for us Mopar, but as you can see, once companies saw what companies like SUperchips can do, they seem to all pop out of the wood work. Some bad, some good.
I don't know about you, but when it comes to safety and stability on my truck, I don't mind waiting a little longer (~1 month) since the original release date. Just remember back to the days of the Superchips release (many people will tell you stories about that and so will the search feature on this forum).
Not trying to start a flame war, but please, be gentle when your speaking about a touchy subject with many people. Maybe you know more than me? Who knows, but if you do, please share. Just don't be so quick to judge.
