rpm will not go up

[306 2.0 16v]

Hello. I'm new here, so have some patience with me.

I have mounted a vems v3 i am running the latest version of firmware.

the problem is that it will not go up in rpm before it gets over 50% throttle. but then comes rpm also up.

It's like as if the control, keep the rpm down until it reaches 50%

does anyone has a good suggestion for what it can be.

Thank you in advance Dennis

sorry for my english
