I've seen you guys say and I've heard the 2005 hemi is the best year for tuning. Why is that?

The 03 has very limited tuning abilities, not much in the pcm can be changed, and there isn't any transmission tuning abilities for shift points, firmness, etc...and I think the 04 is barely better. In 05 the pcms have way more options to change and tune

04 is limited but not like 03s. 03s have a separate computer for trans side 04 up its integrated as one. The 04 lacks trans tuning abilities other than using superchips, but I beleieve the motor side most the tuning abilities are the same as 05s

05s have full trans controls but I have seen threads where some people get locked out of the trans side on 05s. 06+ introduces MDS an something most people turn off in tune when doing performance side of things.

Thanks guys for the input. I've got an 05. But I'm waiting to do some mods all at once. I have a k&n intake and a mbrp exhaust on it already.
