can I 're-jet' my turbo lance to handle a higher flow pump or do I need to buy the full head?

just on secondary note; my new machine is 50bar lower pressure than my other machine but has a greater flow (21lts/min  opposed to 15lts/min) it nearly takes my arms off!! I can't believe the difference in power with the extra flow.

You can replace the ceramic inserts if its a better one but I usually replace the whole thing. Have you considered drain work with the machine
