> not trying to be a dick at all but that sounds completely wrong. your fuel pressure should always be there. it sounds like the pump cant keep up or the mapping is wrong.

we are talking 60psi of fuel pressure vs 900psi of nitrous…which one would get there first even if the lines were the same length? yet along the fuel line being a little longer?

FYI, we dont have “mapping” lol
