im getting the LE1 package done to my car and new RRs pushrods and springs. Would i need to get an LT4 knock module to go along with these mods?
I believe im seeing the correct item on gmpartsdirect. Part number: 16214681

Just wondering if it would be a good idea to pick one up for this mod. Thanks

 

That is the correct part number. If you are using noisier aftermarket rocker arms, then it is a cheap,worthwhile mod to do.

 

Thank you for the reply.

 

I would swap out you knock module to the lt4 one even if you just have loud exhaust. You will notice the difference at high RPMs
