Sounds like you have the wrong thermostat. This happened to me when I installed stage 1.0. My car would never heat up properly and I didn't get much heat in the wintertime. The proper Cosworth stat is supposed to open at 169 degrees F. You can check it by heating a pot of water and measuring the temp, recording when the thermostat opens. My first one was much too low.
I contacted Cosworth and they sent me a replacement and now my car heats up to about 1/3 on the gauge and I have plenty of heat. If I remember correctly, the thermostat I originally had was for a Mitsubishi and it was shipped with the Cosworth package by mistake.
Here is the thread where I had the problem with the stat:
