@Fcuk-Combustion there is a setting you will want to adjust when running a 150watt coil.
Here is info on how to find the setting and what to set it to:
To adjust Auber RDK-300 controller for any 150watt coil. Hold down the knob for 5 seconds, the small power indicator light will start blinking. Turn the knob clockwise and scroll to 166 that is the access code(if you overshoot turn the knob counterclockwise to go down) then push the knob down once to and you will come to P-125, press the knob again to get to I-60, and press again to D-10, press the knob once more and you will come to OTH-40, This is the setting you will want to change from 40 to 67 for all 150watt coils. Press the knob one more time for auto shutoff and set to desired minutes and then press the knob one final time to exit.
Once you change the above. It should help improve the performance as it is set to 100 watt by default
