Super Knock Detected

Pulled out of a corner then drivetrain malfunction and these super knocking codes popped up. I'm bootmod3 stage 1.

Datalogs?

Having a lean code at the same time isn't good really.

Mods? Mileage? Plugs? octane for tune? octane gas you are running?

Ideally you have datalogs, do they show excessive timing correction and knock events? Would suggest a fuel quality issue and you may need lower octane tune and/or better octane gas.

My mechanic said the spark plugs are soaked with fuel. Fuel injector failed. He said compression in all cylinders is fine. Internal damage to the motor appears to be 0. He is doing a smoke test for vacuum leaks.

That's good, its almost important to datalog and make sure your fuel quality can support the map you are running.
