Razer Raiju Ultimate Firmware V1.03 Request

My Raiju Ultimate came with v1.01 preinstalled and was unplayable out of the box with crazy lag. After updating to v1.02b, the lag problem is improved but still not completely fixed as the input lag are still present when comparing to standard DS4 controller and when in wired mode, and once in awhile the controller would go crazy like something interferences with the connection. FYI, Im sitting about 2-3m from my ps4 with nothing in between. So, I'd like to know if v1.03 has fixed the wireless lag problem, and if I can get a link to that. because afterall, I bought this controller for its wireless capability (already have the original Raiju), but has been forced to play in wired mode because the lag issue. I am just disappointed in Razer considering the 200dollar price tag on this controller. Thanks in advance.
