Both Stage 2 and Stage 3 operate well within the engine's tolerances.Stage 2 is recommended for bone stock setup with no intentions of adding any aftermarket exhaust or air intake. Stage 3 is recommended for slightly higher performance on a stock setup, and highly recommended for users with aftermarket exhaust/air or have plans for them in future.
