Is it necessary to run a lt4 knock module in a h/c f-body with solid engine mounts and poly trans mount I`ve heard yes and no! I just wanted to know before I have my car tuned! If yes where is the cheapest place to buy or is there any other tricks I could try!

 

Probably good insurance, but the only way to know if you need it is to find out by a scan or datalog that you are experiencing false knock.
