razer raiju tournament - firmware mod / custom firmware?

I hope this question is allowed here! Is there an alternative to the stock firmware? Why? For example to improve performance. or set the trigger so that several commands can be executed with one action (combo). I'm not talking about continuous fire or other anti-game modifications! I Just care about performance and diagnostic tools, such as the ability to read out the input data to recalibrate the controller, change the dead zones, compensate the analog stick drift and so on. a controller with a firmware... that calls for modding! don't you think so?
