No, there is no update for the Turbo 30. If you have firmware version 4.5 and charge at 5.0amps, you can get 3800mha which is enough for most gp3300.
If you go to 3600mAh batteries, you will need to manually repeak.
There is an update for very specific specific versions of the Turbo 35 BL.
The recommendation from CE is to either purchase a newer charger or simply repeak.
