ive got the sct xcal 2 . i installed the tuner it came with what else can i do with it

 

plug it in your car, turn it on(but dont start), select custom tune.
select the tune. then you should be able to scroll down change the gear ratio, when the fan comes on and off, timing at different rpms, or timing across the board, rev limiters, idle, if the dealer turned it on you will be able to turn off the trac control, or you can talk to him and he can email you a tune that will do that.

thats all I can think of off the top of my head

 

you can datalog with it, not sure how tho

 

if your check engine light turns on you can check the code.

 

thanks for the reminder. read the codes of a friends truck and need to find what the codes mean now...
