Yes, they will sell you a custom tune that you will flash yourself. They will send you an xcal3 preloaded with a tune and will be able to remotely tune you when you provide them with datalogs. They will be able to fine tune and adjust their original tune accordingly from there.
One of the parameters they can change is your ecu governed max speed (or remove it altogether.) That may be useful for track use but not for much else. The main benefits of a tune are increased drive-ablity and performance through the normal ranges and speeds you typically see every day. Please stay safe and responsible on public roads
