I am confused as to why you have fitted a knock sensor?

I read you have a 3dr, which should be on either a L1 ecu or L6. Neither of these support knock sensor input, nor will the loom have the wires present.

Have you changed to using L8?

192@wheels, although a touch low for a stage 1 car is not that far out. I would normally expect around 210@wheels for an average stage 1 car, perhaps 220@wheels on a very good one.

I'll await your answer regarding what ecu you are running before speculating further?
