Frequently asked questions
Do upgrades reduce reliability?
Not when done correctly. Many of our upgrades improve reliability — especially cooling and supercharger components.
Do I need to upgrade the supercharger for more power?
Not always. Intake, exhaust, and ECU tuning often provide excellent gains before major supercharger work is needed.
How much extra power will I gain?
Gains vary by model and stage — from sharper throttle response to significant top-end increases.
Can you tune for fuel efficiency instead of power?
Yes — ECU calibration can be adjusted for smoother, more efficient cruising.
