What about top speed limitation for euro model...

Hi. I search information about a possible top speed limitation on the euro models.

Like my C-Max 150 TDCi year 2015. Normally it takes approximately 200 km/H maxi.

But with my stage 1 up to 200 CV, top speed remains the same.
In 5th and in 6th gear.

After some log, I saw that torque demand is reduced by 20% after 4000 rpm in 4th, 3500 rpm in 5th and 3000rpm in 6th.
Like little limitation to reduce boost and gently reach 200 km/h.

I also mailed some tuners because they talk about Vmax Limiter removed on some Focus ST185 tuned.

Here attached, log in 4th, 5th and 6th gears.
Red is Torque Demand
Green is Boost Pressure
Cyan is Position of Accelerator Pedal
Pink is RPM

Bu sorunu bende çözmek istiyorum, aracım Ford Focus MK3 1.6 TDCI ( 210 Hp + 440 Torq). Dyno ölçümünde 5. viteste 4200 rpm 440nm, 6. viteste 3600 rpm 150nm :( Bir sınırlayıcı var, aracım 5 nci viteste daha yüksek hızlara ulaşıyor. Siz çözüm bulabildiniz mi?
