When you say you are switching to a JB4 and COBB combination, does that mean you can have COBB on top of JB4 tuning? How is that possible with ECU flashes...? I'm confused...
Oh! and I forgot to ask... What exactly is protune for COBB?? Is that just another tuning map?

I've got bigger turbos so it is better to use the Cobb installed on the car as well as the JB4 so that there is finer control over the fueling. The ECU is flashed/programmed with the Cobb and the Jb4 is physically plugged in.
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.
