Exactly what I expected. We should remember that they have a performance division sRT and they are complemented by Mopar Performance. 425 HP is nice, real nice. If you should need more, and I will. Then you can put bolt ons that will put you over 500HP. Thats the reason we have Mopar performance. But a lot of folks want bragging rights to stock HP and performance figures. Chrysler has always answered that with a performance division. So get what you want from Mopar and also won't void the warranty in most cases.
