You shouldnt, If i recall correctly the LT4 Module was need so that the Computer didnt mistake the Roller Rocker Noise of the LT4 as misfire.

If you don't have RRs or headers, you shouldnt need it.

just some boltons, stock manifolds, but this cutout is LOUD as hell and ive heard of people getting some timing retard due to the knock module encoding it as valvetrain noise
