They were saying that the frequency that current resonator is working at causes engine to vibrate but I am not a mechanic

GL anyway!

If your SA says to remap the software. Don't do it if at all possible.

Because in many cases, the updates create more issues than than they solve. I have a same small problem at idle and my SA and I concur: just live with it.

Yes, all under warranty... And when AC in is ON you can feel the vibration through the steering wheel and floor. I got the car back today the SA said the idle value set too low, they increased to around 7000 at idle it was around 6000. it feels a lot better the vibration very minimum now.
