injectors/ fuel management?

[itssr20]

Can you run larger injectors on the stock SR ECU? Or do you have to use some type of management like s-afc or something? Installing my npr ic soon and might want to turn up the boost!!!!

Don't need to upgrade stock injectors to up the boost. But if you want to anyhow you'll need a fpr or injectors and afc.

If you are running the stock turbo you don't need larger injectors to up the boost. You do need to upgrade your fuel pump though. Other than that, with a FMIC you should be good all the way to 14-15psi which is where the stock turbo tops out.

some people say 10psifor stock injectors w/ stock t25-what is the "truth" about max boost ?, thats why i was wondering about injectors, yea i got the walbro though.

You can run 1 Bar fine on the stock turbo, stock fuel, with a Walboro and a FMIC. I have done so for the past year with no problems. The injectors are probably running over 90% duty cycle, but they work fine.

And if you do upgrade then yes you need some sort of fuel management or you will run pig rich.
