Re: Questions on my direct port meth setup
If you use a metering valve like the FAV , you won't need a additional check valve. There is no pressure differential across the jets.
I would even considering installing 0.5mm jets in your case. Disadvantage is yout mapping depends more and more on the WI the more you inject. If you use the car on track, consumption goes up a fair bit as you are on the throttle a lot.
