Tungsten film is designed to correct for the amber tint of traditional incandescent lamps (specifically, as noted above, studio lamps that give off light at 3200 degrees Kelvin). Therefore, it's designed to subtract amber (or yellow, loosely speaking) from the image, not to add it. If you shoot it outside in sunlight (roughly 5500K) without a filter the result will be an excessively blue image. As AGX says, it was intended to render a neutral tone in tungsten light, not to enhance the amber bias.
One of the main uses of tungsten balanced films was the motion picture industry. Kodak 5219, the ISO 500 tungsten stock, was possibly Kodak's biggest seller because the cinematographer could shoot indoors (tungsten light or close to its color temperature) unfiltered, and take the same film outdoors but shoot through an 85 filter (amber-colored) and get a roughly neutral tone in both situations. In southern California, where the sun is bright, there was a lot of use of 250D stock (daylight balanced) because the 500T was too sensitive. But tungsten balanced film will not give you an amber-toned image unless you put an amber filter in front of it.
