Sorry for the stupid question but the fueltech ft450 gives me two maps one for the primary injectors and one for the secondary, I have the secondary’s coming In at 0 vac would it be normal to see the primary map back off at this point then both continue to rise? The reason I ask is the primary map looks like it has a huge dip and it doesn’t look right.

I personally don’t think this is right and I should aim to smooth out the transition, you can’t feel the change while driving. I don’t really have anyone local that could help so thought it might be best to ask here. Sorry for the stupid question.

not sure I could have the secondary’s come in any more gradual.
