loud noise (after turbo/injectors upgrade)
installation went smooth i have a video of the noise

utec txs is the engine managment
even though i am running stage 4 right map that is for 550cc inj
i am running really rich
that still doesnt xplain the loud rattling noise
i also replaced the clutch headers and uppipe at the same time

Sounds like a loose heatshield someplace. Or possibly the clutch wasn't aligned correctly. Either way, I'd get the car dyno-tuned ASAP. You have a fairly rare setup, and I wouldn't trust any base map that didn't come from TXS directly or one of their top dyno tuners somewhere else.

When does the noise happen? All the time? Base maps are notoriously rich, although can have high timing for 91 octane users. Get it tuned.
