Talking Injector Duty Cycle- When do you need larger Injectors??
I started logging my Injector Duty Cycle. When do you need larger Injectors?? I am running close to 90% with stock injectors. Will installing larger ones gain me anything?

80-85% is "suppose" to be the max. If you don't run your car hard all the time, you should be ok.

Will I gain any HP by going to larger injectors?

Nope! Just a little thinner wallet!

Maybe first check your fuel filter isn't blocked.

You might lose some low speed driveability especially if you go the BIG injectors.

But if you readily exceed 85%, you might not have much choice.

Hmmmmmmmmmm...my fuel filter has only been in for ~15k miles, but my IDC is around 85%-88%, and I only have bolt-ons. Maybe I'll replace it and see what happens...
