I'm new to tuning, I bought the V2 suite so I can flash tunes into my customers cars.

When my Tuner sends me a tune am I suppose to do a cal -flash or a full flash?

I licensed the PCM and the Trans Controller and i did a cal -flash and now after i did some more research i'm not sure if that was right.
Also after flashing how do i check to make sure it actually flashed the tune?
