I bought the SHO Power Package from Unleashed but I upgraded my programmer to a Livewire TS. So I'm running colder spark plugs, colder thermostat, and 3 bar MAP. I also bought a cold air intake and a catch can and had Torrie send a 93 octane tune.
I can tell a power increase and so far I've ran it for about a year and half with no issues at all. And since I'm not running a proprietary programmer, I can have my car tuned by others if I ever decided to. I drive my car daily. While I'd love to mod it for as much power as possible, I need it to crank every morning and not leave me on the side of the road.
I don't have personal experience with LMS but some of the guys here have blown engines due to them. Also some of their packaged tunes have known issues. I believe they've corrected them now with updates, but I just opted to go with someone more highly recommended.
