Are you sure the car is knocking?

Yes

Allright, little update here.

There seems to be an issue with Ecutek after flashing the car, registering abnormal amounts of knock.

At a certain point, I got the tip to unplug the two ECU connectors in the passenger footwell after flashing the ECU with a new file. This helped a lot and removed 80% of my knock.

Right now, the only moment that I have timing retard is when I go in boost in low RPM (say 3000 to 3500). The car doesnt seem to like 12 degrees of timing there (at 6-13 psi). I think it's "lugging" the engine and it pulls like 2-5 degrees of timing depending on various conditions.

I think its a combination between stock high CR + building boost + requested timing - in low RPM's.

I would be interested knowing what timing retard other people run in the 3000-3500 range on stock block and 93 pump.

That is definitely way too much timing. I usually run half of that at that RPM range as it's better to be safe than to throw a rod out of the side.

Sounds like a case of the tuner not knowing what the car needs.
