The DSP does WONDERS for the 09+ 4.7L as well. For a few hundred dollars, you get the same/better HP/TQ #'s as the 05-07 Hemi, from less motor.
Not to call you out or anything but I don't think this is correct....I think what you are assuming is the diablo numbers are roughly the same as the SC numbers, which makes sense. So say 50hp, 55lb ft added. And you are adding that to the stock 310hp, 330lb ft. This gives 360hp, 385lb ft. This isn't correct though, because the SC numbers are a MAX gain, not peak gain. the peak gain is about 15hp, 30lb ft if I remember correctly, so it would actually be 325hp, 360lb ft....
