HHO in diesels

[hogwater]

Hi I will be doing a setup for an older and then the newer diesels both are PU's one a cummins and one a chevy.Any input or ideas on size and best place to install the input in the intake side,both are turbos.Also looking for some o2 info on the chevy its an 07.Can the hho be used like the lp in the diesel to get a betterand longer burn and not have a bad effect on the injectors?
