Default Porting the Throttle Body

So if I have my throttle body ported and polished, will I have to get the car retuned? A freind says yes, when he ported his throttle body, the idle was very poor afterwards. He had to retune it.

My fuel trims were definitely worse, but as for idle it was fine. Probably depends from vehicle to vehicle.
