Or are you wanting questions regarding 3800's?

They are a bit aggressive. Increasing the voltage in which is needed for the pcm to register knock helps with this. Most pcm's are set right around 120 mv. I will turn the voltage up anywhere from 300 to 400 mv's depending on modifications to the car.
