sounds/looks like a piggy to me:
"The Hartge 'Engine Conversion' is a bespoke tuning module that plugs in ahead of the engine computer on the wiring harness. It has factory-style plugs to connect in-line with the water temp sensor, fuel rail pressure, turbo boost pressure sensors, turbo wastegate valve, intake camshaft sensor, 12V power and ground. The module then sends a modified signal to the engine computer allowing it to increase boost by varying amounts depending on load, engine speed, and other factors."
