Plus Map

Boost up to 1.3 bar. Earlier boost onset. Lambda optimised.

The Plus Map is a significant step up in performance. Boost pressure is raised to 1.3 bar with a revised boost curve that brings power on earlier in the rev range — the engine pulls harder from lower RPM, making overtaking and motorway driving noticeably more responsive.

Lambda targets have been adjusted to optimise the air-fuel ratio across the entire load map, improving combustion efficiency and delivering more consistent power throughout the power band.

What changes:

• Peak boost pressure increased to 1.3 bar
• Boost onset moved to lower RPM for stronger mid-range pull
• Lambda map revised for optimised stoichiometric ratio
• More linear and predictable torque curve

What stays the same:

• Overboost management at factory settings
• All factory rev and temperature limiters retained

Best for: Enthusiast drivers wanting real-world performance gains, track day use, cars with a healthy standard clutch.
