fuel injector question
as of right now i have the stock injectors running at 58psi with a bbm fuel rail, a adjustable fprand a stock ko3s. according to this http://www.megamanual.com/v22manual/minj.htmif i plug in 170 (basic crank power) plus 30 (avg chip adding power) = 200 it says i need 310cc injectors is this true? will i gain anything by getting 310cc injectors? or should i just stay with what i got
i really don't have an idea of what chip i have. My car had a 5bar fpr when i bought it

RE: fuel injector question
you are running at ~4bar which puts the stock A4 (286cc i believe) injectors to 310cc at 3 bar already. Your fueling is fine. Even though you do have a fuel rail thats not needed [8D]

RE: fuel injector question
Why did you take out the 5 bar and buy a adjustable to turn it down? I noticed on the 01',that the fuel trim at 4 bar on the high rpm is not the best and the 5 bar or equal psi helped that a little.

i had tha 5 bar on and i was running really rich...but i was getting better boost....so i put back on the 4 bar (like told!) and its not running rich but less boost

i didn't intend to turn down the fuel pressure when i installed my adjustable frp and my fuel pressure gauge i installed the gauge first theni started the car with the 5bar frp in, then looked at what psi the gauge read, then i installed the adjustable fpr and ajusted itthe same, but at the time i had a leaking fuel rail without knowing it. So what psi shoulda 5 bar fpr be at???

RE: fuel injector question
a 5 bar is at ~70-72 psi. You could try running the adjustable at 65psi if you don't want to go so high. The stock on the 01' is a 4 bar to begin with. Maybe you thought it was a 5 bar? 58psi is a 4 bar.
