PCM = Powertrain Control Module (It's the computer that controls your car...also known as ECU or Electronic Control Unit) It's what gets programmed when you get a tune.
TBS - you got me on this one. TPS is usually a throttle position sensor - TBS could be throttle body sensor? Not sure.
MAP Sensor - Manifold Absolute Pressure - Measures the amount of air pressure in the manifold (or wherever it is positioned) and is used to adjust the Air/Fuel ratio going in to the car. Similar purpose as to a MAF sensor but doesn't measure airflow...just pressure.
PCM Programming - See above
KAM (From Google) KAM stands for Keep Alive Memory and it's a form of adaptive memory. KAM memory works as follows, whenever you drive your vehicle, the car's E C M or engine control module learns each sensor imperfection, and records it on a special memory.
Livernois Kit - I'm assuming refers to the tuning package from Livernois which can consist of a lot of combinations but primarily means the tune, thermostat, 3 bar MAP sensor, and possibly an intake along with plugs gapped appropriately.
HTH Hope that helps...
