i'm not an owner, but i do read alot
1)it seems they do a basic 'spring mod' that has boost peaking around 17 and drops to around 14ish at redline.
2)the 'drag srt' uses stock block and other parts too..but i dont know what #'s its running..also there is a person that is already in da 12's, srtgurl or soemthing like that on the forums.
3)dont know about the mistu turbo
4)the mopar stage kits are under warranty, maybe if professionally installed...but i know they are
FYI - First mod should be some coil-overs (lol)
