PNP Upgraded Injectors for NA Build?

Been looking into this as well as I'm wanting to run Flex Fuel in the future at some point.

I came across the 225 8N Audi TT (0280156063), uses EV6 style injectors just like us. I have no dimensions to say how close they resemble the OE injector fitment but visually they look very close. Rated at 386cc it should bring you down atleast 17-20% IDC comparing to the stock rated 268cc.

Corey, what are the ones I have on mine? Welcome to have them.

Nice number, looks like you owe lang an apology LOL!!

Just kidding 🤠

Lol I don't think it would have made these numbers if I didn't have my local machinist catch the leaking valves before I had him swap them. But I will give Lang's machinist credit for the pocket porting.

Just finished my engine build and made a respectable 370whp on a mustang dyno which is excellent but my flow matched stock injectors are maxed out and I need to upgrade to something with more flow. I was recommended at least 440cc like the bosch green giant as well as 550cc but am looking to see if there are any options that are a direct fit to replace the stock ones in terms of fit and connector type as I don't want to have to run adapters or reengineer the electrical rail harness. They need to be the same spray pattern as stock as well so the car will idle properly.

Does anyone have any recommendations for an NA build that sees street usage? I don't want any bs with fuel trims when not at WOT. I know injector dynamics is a go to for S54 but they are way too big for an NA car.
