Default Power harness
has anyone else tried one of these. I have, and I am worried about adverse efffects on my engine besides bad mileage and smoke. It dose help low end power but it makes the engine smoke like crazy. I think I going to remove it. It connects between the manfiold pressure sensor and the ECM so it does something to the singal being sent to the ECM.

All it does is trick the ECM into thinking it's making boost while it's not. I'd get rid of it.

There really is no point in running it.
