The whole point of doing this mod is to delete the expensive, heavy, and annoyingly placed air pump. This will give you room for a turbo, and save you weight. Plus save you money as it’s cheaper to tune and delete than it is to replace with factory parts.
Locate the air pump
Disconnect from car and from secondary air valve
Disconnect secondary air valve from engine block
Do something to fill in the hole where the valve entered the block (weld, plate, etc.)
Run custom software if not already done
