My IATs were high cause my coolant was very low, separate issue that was fixed. Turbo coolant line was corroded and leaking.
Can you explain the knocking below 2k rpm? I monitored my knock sensors with ISTA and saw the entire time i was driving they were way above nominal voltage. 4.5-5.5V is normal according to ISTA and when i accelerate all of them were hitting ~20V.
I also noticed my ignition timing for different cylinders ends up being way off when i accelerate. Could this be an issue?
Also I only use 93 octane and have filled up many times at different stations since this started happening a month ago.
