Most of the the direct port checkvalve jets are custom made to order based on flow.
The 110c is based on the 0.4mm jet. There are three steps A, B C. Correspondent flow is 92, 110, 140cc/min. (C= standard). All flow rates are calibrated at 150cc/min.

There is a comment option before final checkout. you just ask for the desired flow and we will do the rest.

If you are only using 55-60% DC, It will advisable to set the pre-amp stage to x1.5 and alter it later when you higher power goal is achieved.
