The current supercharger code is old, and strictly RPM based, and I don't have a good solution. The EGT calculations changed slightly in the last (2.5) release, and will change again (already in git) in the next release, so they may be more accurate to use as a base for TIT. As I understand it, TIT is exhaust gas temperature measured before the turbo and EGT is exhaust gas temperature measured after the turbo, so TIT will be higher than EGT. The temperature difference should be somewhat proportional to the boost ratio. The more boost being produced, the higher the back-pressure in the turbine impeller, and higher pressure implies higher temperature.
