rb20det afr

[RBKIDD]

so i got my tune back and im trying to start the car i get it started and i really cant get it to idle at all. my afr is 12.6 at 3k rpm idk if that is too rich because the spark plugs are like saturated in gas and i can always smell gas. i have 550cc injectors and a walbro 255 fp. also has nebody had a knock after doing cams and valve spings just seems lik eth evalve train is just a lil loud, at least its not a bottom end knock.

I've found a lot of aftermarket injectors to be crazy loud. That might be what you're hearing. Did you use a resistor with those injectors if they needed one?

What are you using to compensate for the larger injectors?

[RBKIDD]

other than my rom tune i dont have ne thing else for the injectors. i nvr knew that i needed other stuff. what do the resistor packs do

[RBKIDD]

so if my new injectors are high impedence injectors then they are ok,but if they are low impedence injectors then i need a resistor pack?
