I’m getting ready to install a set 150% over injectors in my lbz duramax I have the flow sheet for the new injectors and the flow sheet has only flow rates at 30, 60, and 180mpa fuel pressure test points and of course the pulse width table in ecu has a lot more. Is there a way to use the test points on flow sheet to get an idea of flow for the pressure rows not on the flow sheet?

The closest thing you can do without a more refined flow sheet is to broadly interpolate between those rows and columns not mapped on the sheet. As rule, I'd avoid messing with the pulsewidth table at fuel flow rates below 40mm3 to start. The area usually only needs very fine adjustment if any.

Ok I will try that, thank you Nick! I did notice that at 60mpa and below there is very little difference between the factory injector flow rate and the 150% overs.
