Does anyone know if you have to retune for an lt4 knock module? Or is it just plug and play?

Do you have full roller rockers? Do you have scan data indicating you are experiencing knock retard?

Naw future mods will be 1.7 full rollers aluminum and springs. Although im not sure if i can get away with a 1.7 on a stock cam.....should be interesting. I know ill need the springs for sure. Before all this though im still getting a new ignition system.
