    Thanks! Just thought i'd help out as much as i can, i'm more mechanical smart then tune smart.

    I'm going to be installing my knock sensors next weekend, i can take more detailed pictures and instructions then if wanted. Just let me know and i'll bring the camera, i might be able to take a video as well of the whole process and time lapse it possibly.

    On a side note, be sure to buy new intake manifold gaskets! Not something to cheap out on there!

    I just logged my 04 Suburban 2500. It is throwing P0332 Knock Sensor code. It is most deffinatly using the low octane timing map. But my log shows no knock retard in 20 minutes of highway driving. I need to replace the knock sensor and harness. But I need to go to Maryland this weekend. I will just live with it till I can get it torn down.
