The TS6153 has a resistance range of 15.2-19 ohms

The TS6628 has a resistance range of 22.7-25.5 ohms

A big difference when it comes to indicating on a gauge.  That's why

your gauge is pegging.  Try the TS6628, you should see a much closer

reading.  Or, as an alternative put a 7 ohm resistor in series; the

proper sending unit is the better choice.

An alternative to using a 7 ohm resistor with the TS6153 is to use a 10 ohm
potentiometer. That way, you can calibrate the gauge to the sending unit.
Unfortunately, this requires some fairly accurate temperature sensing device
to calibrate the gauge against. Once you have the gauge reading accurately,
by adjusting the pot, remove it (the pot) and measure the resistance that
was needed to get an accurate reading. Then, buy the appropriate resistor,
or resistors, and install them permanently.
