When do you need to upgrade your fuel injectors? Just wondering.

Thanks.

 

When your injector duty cycle is above 100%, if you can log. If not, I would say stage 1+ is a good approximation of when you will need them, also depends on type of boost controll. If using "ecu controlled boost, you are likely to use a lil more than say a MBC.

 

how about you're using a ebc and setting the boost above the stock settings?

stage 1 as in...

intake
TBE
LICP
UICP
EBC
255lp Fuel Pump?

if so which cc fuel injectors?

 

anyone?

 

A wideband will tell if your running lean which would be the only reason for upgrading injectors I would think, unless you want to run a lower duty cycle; you can probably compare people's setups as I'm sure tons of people run the same modifications you have, but I don't have an Evo so...

 

+50 The only reason to change them out is when you are maxing out the stockers. There is no set HP rating or mod list.

 

IMO once ur IDC is above 90% i recommend changing injectors.

 

Stock should be maxed out before changing.
