Includes everything in the Basic Service plus:
- Stage 1/ Stage 2 Cam Tune (as needed)

- Power gains are with stock parts (manifolds, cats, etc). They are estimated/typical and require premium 91/93 octane fuel.
- Final results depend on your specific setup, but these numbers are based on our real world experience.
