how do you fix the knock problem from forged pistons and rods. I'm picking up a lot of background noise from the knock sensors in the lower rpm levels and its pulling -5.0 degrees of timing. I'm using cobb software and have the option for adjusting back ground noise as a smoothing factor but struggling on the direction to adjust it.
