Injectors real noisy

I need some input on this. I replaced my turbo with a MTW stage 1, I'm running Innovative Diesels Extreme street tune, 40hp FICM tune. The truck runs great, pulls hard, up to half throttle,anything past half throttle when the boost comes on the injectors rattle really hard. I think it is starving for fuel.
My question is, what do you all think? I have the blue spring upgrade, the rest of the fuel system is stock.
I have a SCT Livewire on the truck, where and what do I need to monitor the fuel pressure on the anolog inputs.

You have to adapt a sensor into the test port and read the fuel pressure. What's your egts when you get on it hard and what size injectors?

The injectors are stock, I did not stay in it long enough to notice EGT. Sounds like real bad detination, in a gasser. I've just been easy on it, not to tear anything up. I will hit it in the morning and make note of the EGT. I have removed the extreme tune tonight, it is just the FICM tune in it now, and it still rattles.

No codes, no check engine light, just does no sound correct. Where can I get the adapter for the test port, and the wiring to tie it into the livewire? I know I can get the sender on ebay, seen someone posted it on here awhile back.

If it throws a code, will it set the check engine light? or do you just have to check for the codes? I have a snap-on scan tool at work, I can check it out.

Scan it and see what it says, any chance you were low on fuel in the tank?
I honestly do not know how to set it up with the live wire. I believe it's an m12 but don't quote me on it. I had that setup along time ago can't remember the sizes though

I'm not sure it is the injectors, but the only time it does it is under hard acceleration. I will check it out tomorrow, and report back.

Is it a screeching sound? Very high pitched?
