A protune is a custom map done by a company tailored to your specific mods or requirements. Some tuners do theirs on a dyno to acheive the best results whereas others email you the map and work off customer feedback.
lol, me too. Not much to do at work so I have been researching forums all morning. But it was a hard to wake up this morning after 5 day weekend...

Anyways, thanks for the explanation. so you CAN use COBB AND JB4 at the same time for finer controls?
