I am located around I10 and Gessner. Im actually not using it in an LT1/LT4 powered car. Ill know in about 1/8th of a mile worth of driving whether or not it is going to work for me (making my purchase useless or valid).

Think I could try one out? I can swap the module in about 2 minutes and drive around while scanning to see if its working with my PCM correctly.

What is it doing? Do you need to turn down your knock sensors? I can do that with tuning.

I actually have an 11 second turbo Grand Prix and the PCM knock modules are the same style of connection for the knock sensor. I have a lot of what appears to be false knock on my car at VERY low throttle % and I believe the valvetrain noise and/or something else is to blame.

I actually have tuning hardware but Ive been told the LT4 knock module is compatible with my PCM and that some people have had good results. The LT1 module did nothing for me except throw a code for the front knock sensor.
