does anyone on here use TTS mastertune?

i was given a laptop with the software on it already from my friend who tuned my car but now has an LS1. i've played with the program before and changed some basic stuff. (EGR, Rev limiter, line pressure etc) but i would really like to get into the tuning part, like the spark maps and the like

does anyone have a user's manual or a link to where i could view one? i know some of the basics of tuning, and i would like to get a better tune for my car as i plan on upping to a 150 shot here real soon.

thanks for the help!
