I bought an 08 TE510 with power up kit. The O2 sensor is still there but the wires are not connected. What is the advantage of putting the plug that comes with the kit in rather than simply having the sensor disconnected? It seems to run well, but I may not know the difference. Thanks!
Only advantage I found with my 310 was avoiding damage to the expensive O2 sensor! If you have the plug, I'd use it, if not, not likely going to notice any performance difference.
The O2 sensor has an internal electric heater that keeps exhaust gas from condensing on the sensor element. The internal heater can get as hot as 1000F. If you leave an un-power O2 sensor installed for a prolonged period, it can be damaged. Best to remove it. On the 08's if you need to make ECU FB1 fuel adjustment, you do need to temporally reconnect the sensor.
In addition to that i would guess you get slightly better flow from the pipe with it out. Husky are notorious for having restrictive (quiet) pipes to start with.
