Default Car sounds horrible after walnut blasting and tgv/egr deletes

Video example
https://drive.google.com/file/d/15OU...ew?usp=sharing

Any idea why the engine sounds like this after a walnut blasting, tgv/egr delete, and a grimmspeed EGBCS were installed? Or is this normal for a car to sound without a tuner's basemap?

The noise seems to lessen after 10-15 seconds and the ticking stops altogether when the throttle is pushed in but returns when idling.

I am planning on changing the oil this weekend and bleeding the coolant. Any other suggestions to do? Is there a diagram that shows exactly how the intake manifold is supposed to go on in case I missed something? Is this normal if you have not applied an egr/tgv delete tune yet?

I think I may have left a bolt somewhere near the EGR delete which hopefully explains the ticking (and not actual rod knock)

Did you have the exhaust manifold off? It could be a leak at the exhaust flange or some kind of exhaust leak very near the cylinder.

Heat shield? Might be off just enough that when it cools it hits something, but is clear with engine torque and heating up?

Definitely sounds like an exhaust leak. At least, that's all I can hear in the video.

Thanks for the input! To fix an exhaust leak I would just trace the source from the turbo to the turbo back right? Or would I try and find it elsewhere?

You mentioned EGR delete. Sounds like your block-off plate for EGR port on the head is leaking. Did you use a new gasket on the plate ?

Yes here are the codes (Applied the tune today):

P1492
P1494
P1498
P2016
P2021

Also is this normal to have these codes thrown for a provided basemap to get the car to my tuner before a dyno? Did they forget to remove the codes?

I did install a new gasket for the egr delete. I wonder if I put the gasket on backwards I'll check today.

Well Iím guessing:

Those codes point to manifold and EGR system
Itís possible manifold leak (bc of something with gasket) this in turn, giving false readings to EGR system

Very possible tht sound you hear is cylinders coming through that leak

Thanks guys! The sound was definitely the lower egr plate. I sealed it up properly and now no more noise. I'm still getting those codes but I did some research and it looks like those codes need to be turned off by the tuner. Taking it in tomorrow for my dyno so I'll check with the tuner.

Dyno tune was a success! Said the installs were great minus not torque'ing the skid plate but all went well.
