A method for customizing a materials handling vehicle, the method comprising: receiving, by a processor of the materials handling vehicle, logon information to identify an operator logging onto the materials handling vehicle, wherein a valid logon is required in order for normal operation of the materials handling vehicle; and implementing, by the processor, at least one customization function on the materials handling vehicle based upon the received logon information by: interacting with a transceiver on the materials handling vehicle to wirelessly communicate the received logon information from the materials handling vehicle across a wireless computing environment to a corresponding server, where the server stores customization parameters that are utilized to customize one or more features of materials handling vehicles in a fleet of materials handling vehicles associated with the server; receiving from the server, specific customization preferences that are uniquely associated with the logon information, which the server retrieves from the stored customization parameters that are associated with the fleet of materials handling vehicles, where the received customization preferences include a performance rating from the server for the operator logged onto the corresponding materials handling vehicle, wherein the performance rating for the operator is based on monitored measures of operator capabilities; and interacting with at least one component of the materials handling vehicle across a materials handling vehicle network bus to implement the at least one customization function based upon the received customization preferences, including implementing performance tuning of the materials handling vehicle by: communicating instructions from the processor to at least one vehicle component across the materials handling vehicle network bus to selectively limit, disable or configure the performance of at least one feature based upon the performance rating associated with that operator. receiving, by a processor of the materials handling vehicle, logon information to identify an operator logging onto the materials handling vehicle, wherein a valid logon is required in order for normal operation of the materials handling vehicle;
