You’ve finished tuning up your engine but you find that at full throttle the engine splutters or stalls. When you get the car on a diagnostic you find that the knock sensor is kicking in to protect the engine.
Engine knock is a condition where the fuel inside the engine ignites prematurely and occurs within an engine running at high compression. (It can also be caused by other factors including low octane/poor quality fuel or hot spots within the engine.)
Clutch tuning: performance clutch modifications and triple plate clutches setup
The clutch takes the engine power, and puts this down through the drive shaft, to the driven wheels on the road but allows you to disengage the engine whilst performing a gear change.
Contact like this requires a lot of grip and a fast response. The more power you have the harder it is for the clutch to operate.

Particulate filters and FAP Performance gains.
The particulate filter is a stand alone unit. It is located upstream of the cat in the exhaust system and its purpose is to remove soot particles from the gas stream. The cat the proceeds to do its usual job of converting CO to CO2 and is in no way dependent or relied upon by the particulate filter.
In diesels the cats are two way devices and run in unregulated mode (ie. no O2 sensor like a petrol car).
