Ford Focus 2019 (mk4) 1.0T ecoboost 125 hp 0-100 acceleration 

I think it has something to do with the torque topping and dropping off quickly at 5500RPM, or it might have something to do with driver error. Who knows.

The torque starts to fall at 4500 rpm all the way to 5500 rpm, so, its smart to shit at latesta 5500 rpm otherwise is a loss of fuel

Same focus driver there. The RPM limit is set to 6200, but the faster you are, the lower it is. And, there is no actual need to Rev that much, cuz the turbo starts working on 3800, best performance is about 4100-4500, then it starts to loose, but on 5500 it is still going with less power, then on 5800-6100 there is no actual point in it. Btw, there is no ecu speed limit on it, and I gained speed 220kmh, I DON'T. .... KING KNOW HOW THIS HAPPENED IT IS 999cm OK, turbo engine, HOW TF IT GOES 220, I DUNNO. I've got a BMW G30 520D, on a stage 1, it has about 230hp, and it goes 245, BUT FOCUS HAS TWICE LESS, Weight - 1130+-kg vs 1650+-kg
