However, personally, I would just go intake manifold port injection. I was told the fuel filter only needed if the car sits a lot, so I skipped it since I daily the car. As for the gapping, I'd maybe try gapping down to 0.025 since you're upgraded turbo, and try gapping down more if needed. Keep in mind, I'm running a 0.020 gap on 97506 spark plugs and OEM Bosch injectors on a stage 3 EFR turbo with intake manifold port injection at 660whp.

I don’t want to do any of those things.
Just trying to figure out where the stock injectors max out based on whp & various Emixes, bc I don’t plan on adding more power.
