Ive got that on my truck and I couldnt tell a performance difference but it gave me a great place to hook up my boost gauge so I could put a boost fooler on and still know what my real boost number is. It will not mess up the truck and what it replaces is not a sensor, its an Air intake heater. In colder climates it, as the name implies, it heats the air in the intake. (Not tryin to be a smarta$$)
