Incorrect conclusion. The problem lies with your implementation.
Your pump would probably push around 8 to 9lpm in a full setup at a guess. This is dependent upon the restriction of the block, but let's say 9lpm.
Your total jet-hole orifice area is 132mm^2. At our guesstimate 9lpm, the pump is pushing 150ml/sec, for an average nozzle velocity of around 1.1m/s.
1.1m/s is pretty sedate, and is slower than the rate with which water will flow through something like a Maze 3, which would typically be up around 1.6m/s for a pump like yours in a full system.
Compare that to my block where with an Eheim 1250, the average nozzle velocity in a full setup is around 4.5m/s. With the Iwaki MD-30RZ, it's up around the 7m/s mark.
ie. your holes are too big. Make them smaller.
