Unlock Your Engine's Full Potential
COBB Accessport V3 + BOOSTane Professional = Maximum Performance & Tunability
The Accessport V3 is the world’s best-selling, most flexible ECU tuning solution—now with full TCM support and a high-resolution, customizable multi-gauge display. When paired with BOOSTane Professional Octane Booster, tuners can safely run aggressive timing maps, increase boost, and optimize performance for big-power builds or race-day conditions without switching fuel types.
Why BOOSTane + COBB = The Ultimate Tuning Duo
BOOSTane Professional raises octane up to 116, enabling:
- Safer high-compression tuning
- Knock resistance under aggressive timing
- Cleaner combustion & reduced carbon buildup
- Protection from ethanol corrosion
This unlocks the true potential of COBB’s custom calibrations, allowing you to:
- Advance timing for more power
- Increase boost levels with confidence
- Run higher-performance maps without engine knock
- Make meaningful gains with bolt-ons and tuning—no race gas needed
