    Do larger injectors exist for 3.7 I5?

    Not having any luck finding any. Do they even exist? If not specifically made for the I5, does anyone know if any other injectors will fit? Or any recommendations on someone that can customize the stock injectors? Maxing the stockers out at 109% duty cycle!

    What about TB injectors?

    Can't tell the rating without some math I'm too sleep deprived to perform from my stock TB tune. I show 0.20749 in liters for g/sec under Fuel control/gen/inj control/inj constant if that helps.

    wouldnt 100% be locked open???

    i dont see how you are hitting that high of a number. most i've seen on our trucks is 80ish%. thats pretty high in my opinion for any vehicle with just bolt ons.

    Nope. Do not get to go WOT that often for that long of a time. It occurred at 6250 RPM @ 96 MPH
