right guys ive got an adjustable boost sensor that is set to 15psi, ive diconectd the blue and brow plugs from the back of the manifold.

Which sensor should i have left in place?

And which sensor do i need to run the wires from the boost sensor ie earth the blue plug and have a broken circuit positive feed from the boost sensor so that when the bost sensor kicks in at 15psi this makes up the circuit activating the cold start (fith injector) so that i can go from 14psi to 17 psi

chears Paul.
