By what Wizards said to me was, the solenoids need to be in the coolest area of the engine bay, heat will reduce the effect of the gas, releasing the oxygen earlier before it reaches the cylinders. It will as far as I can gather will be a little like a reduced bottle pressure. As I say this was Wizards words quite some time ago when I went up there with my install.
Fair cop though with the jet placement, good idea.
Yeah Dan was telling me his working history, rather impressive.
