True, the Flashpaq 3815 works on 04-08s, but has far less features on '07 & '08s. Not saying it doesn't do anything for you newer truck guys, or isn't worth getting, but you should know there are many less features before shelling out your dough.
The Flashpaq forum is loaded with posts from unhappy guys who bought it for their newer Hemi not knowing it lacked many features available to us 04-06 guys...

 

Thanks for the heads up hammer! I didnt know...

But the whole point of this thread is to let the guys who dont have oneknow that they can get one locked for cheap and pay $100 to unlock it. $160 out the door is not bad (especially when dude had is original receipt, showing that he paid almost $500 for it)
