Dissatisfied with performance

Hello everyone, am not satisfied with the performance of my v6 at all, seems to me rather like a good 4 cylinders. I already know that it is about 1500 kg which it pulls but that is quite thin what comes out of it (except the consumption of course) from 160 to 210 can work next to it!! Is it also like that with your cars or is it not true with my what?? what else can I do to exclude “mistakes”? otherwise I am already satisfied with the space and equipment but the power of a V6 it is not really greeting carlos
