I think your controller is dodgy. The gauge looks like you're getting full power but you're not - flat out in sixth you should be looking at just over 1.5bar turbo pressure but you're getting about 1.25. if I let off the throttle a tiny bit, i.e. just to the point where the gauge is full but I'm not flat out, I get similar speed/turbo pressure to you... Do you have another controller you can try? Lucky it's a turbocharged car really or it's be very hard to notice!

Yea I see what you mean now compared to kimsters video, il try buying a new car etc & swap out pad see if that works 😢
