Loud ticking noise....
Is there any way this noise could be my injectors?...
i'm wondering if the wrong imped. injectors were installed....
it is NOT detonation, it's comming from the turbo side, the AF is at a rock steady 11.5:1 AFR, no blip in power, no nothing, but there is a slight bump in the drive train....
here's the video:

I couldnt really hear anything. I assume your familiar with the screw driver method of finding noises? 
Checked all the belts and stuff? You'll have to pull them off and inspect them carefully for cracks. They'll tick like a **** sometimes.
Good luck.

It sounded like mid band detonation to me.
The knock sensor is catching it & retarding the timing.
You're lucky it happened at mid revs and the driver lifted in time.
To test, push the CAS back 2-4 degrees & try it again.
My first engine was doing the exact same thing.
I didn't catch it until just after it happened again at higher revs and I broke the corner off an apex seal.

yeah i got it on the dyno to cause the noise and such, and there was no change in the AF ratio or anything....
it comes from the turbo side too....
it also happens at half throttle and full throttle....
and causes the noise easier when i'm going up hill....
* confused to all hell *
oh, and the timing was checked, it was spot on for leading coils and retarded 2degree's for trailing....
