HP tuners is PC based, so you need the laptop. It may seem intimidating but you have full access to change everything that's tunable. You can adjust fuel, timing, ect.

I was told back in 06-07 by PCM for Less that HP Tuners is what they used. They must have bought a large blanket license!
At that time I figured rather than investing in the software and figuring out what worked for a one time shot I just bought a PCM from them so I could swap when I wanted.
