When To Upgrade Injectors?

[InfamousEclipse]

I have the HRC 16G settup w/ a custom, FMIC... I am running 9psi and am wondering at what point I should upgrade the injectors?

Also are stock GST injectors worth the hassle of making work due to the low impedience?(sp)

Ive read a little on low and high impedance injectors. From my understanding your ecu has to be setup for low impedance otherwise the injectors can burn out the injector drivers on your ecu. Can anybody else help out?

How long have you been driving at 9psi for Infamous? I remember my stock injectors (with 80,000 miles on them) started to go to crap and needed to be replaced about 4 months after going turbo and driving at 7psi at first. I then got the Hahn Racecraft 310cc injectors, they really aren't that expensive for injectors, and very worth it The Hahn guys might even suggest a different size injector for your setup and boost level.

Wish I knew about the stock GST injectors. I just went for the Hahn's, they own. But driving with that high of boost (9psi) on stock injectors, won't be too long until things start to go lean (nottt good).

I only had it for 3 WOT runs then my clutch blew. I havent driven it since... (ECU problems now, my car hasnt ran for 2months)

But when she runs, thanks for the info... looks like new injectors are next... I don't want to try and make the GST ones work
