RON 98

AT in manual mode on 3rd gear from 2000 rpm with DTC full off. From 2000 rpm good acceleration, but while accelerating after 2400 rpm, it felt like the car had cut accelerating. After 6000 rpm I heard superknocks, CEL appeared on the dashboard. Then I released the accelerator pedal and shifted into higher gears.

Timing corrections

Charge pipe change from silicone to aluminium with reduced diameter. Change engine oil from 0w-40 to 5w-40. No significant observations. This is Map 1 in for reference in case u need it
