Ok so when me and my boss were tuning my truck we noticed that every time I got on it it would throw any where from 3 all the way up to 5 KR's. My boss is saying it is because my exhaust is too damn loud and since it is dumped it is giving me that many KR's. I know I can unplug my knock sensor and that will keep my timing from retarding but I dont want to f**k up my motor by keeping it like that and i dont want it to turn the CEL on and put it in safe mode. I am going to have a Y-pipe built so I can at least put a muffler on but I want to know for the time being WILL it mess up my motor by leaving the knock sensor unplugged?
