I’m not sure which driver you have and I’m not any where close to being the most experienced person here. However, if you have one of the h17f or h17fx then I think here are the instructions you want. 17mm DrJones H17Fx Driver w/ lucidrv2 - 7135 + FET
Scroll down and you should see them. I think my driver came programmed with something like 3 modes and none of them were turbo. So it might be that the turbo mode is not set. It may be worth checking the thermal control too. I hope that helps.
