I have been reading up on tune options.
Is this ESS tune the one that comes with the handheld programmer?

Do i need exhaust? or anything, or will there be decent HP/Torque gains with just a tune?
I prefer the tune with the handheld, so you can pull tune before dealer service. If BMW Service happens to flash your ECU, the tune would be lost??? Right?
