smatrys are able to add 180+ due to the fact that you are able do custom tuning witch makes me ask a question rumor has it that EFI live is coming out for dodge? If so i would say that is the way to go.
Depends on what you want to use it for... and that still leaves it up for debate. The top 4 in no particular order IMO would be the Redline box(or FMS), Smarty, Drag Comp and Smarty.
