2018 OR 2019 L5P will need an ecm reflash to correct the gear ratio and attempt to correct the tire height, most likely he is looking at $5k or more to have that taken care of due to how the L5P have to be flashed now.

Its not cheap to retune/reflash anything past 2016 LML

Dealer may or may not be able to help with a BCM reflash
