ok, my car has hellacious KR under even 5 lbs boost (sometimes seven lbs here) and ive seen it hit 13 before at wot. keep in mind i NEVER pull any boost with this car these numbers were just from testing while trying different stuff to fix it, namely checking fuel pressure at wot and 15psi. my plugs have never look damaged from knock, and i run 60 psi fuel pressure at wot, i know the exhaust hits the exh manifold so i figured that was the source of my knock. but today it was nice and wet out so i figured i'd pull a couple lbs up this hill and see how she did. perfect, no KR, i tried it a little more and never saw more than 1.9 KR. although i did see the rear of my car tryin to pass the front end( its wet and my tires are generic z rated) Any ideas on this one? ![Confused :confused: :confused:](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f615.png)
