The Basics:
SCT Chip: Programmable, you need to remove your computer sand down contacts to install it, theres many how to's. You need to physically remove the chip to reprogram it, and removing the chip returns you to stock.
XCAL1: Programmable, you need to plug into the OBDII connector and "upload" your tune to your ecu. You can get email updates for tunes from tuners (for small changes), you don't need to remove your computer, etc. You can modify your tune slightly via sct software (ie rev limiters, etc)
XCAL2: Same as XCAL1 + ability to scan codes, scan ODBII parameters. You can also do some mild modifications via the hand held tuner if your dealer has unlocked that for you.
If its a blue SCT chip or a Diablo chip i'd stay away from it because it has little to no support for tunes, etc.
