The HKS exhaust gas temperature (EGT) gauge is the best mid-priced unit we have ever used. If you have a turbocharged or supercharged car, a high quality EGT gauge is critical for engine tuning.
The HKS EGT gauge reads from 500 degrees Celsius to 1200 degrees Celcius (which equals approximately 932-2192 degrees F.) It features a 30 second record and playback mode, a multi-stage warning light function, and a peak-hold readout. The record and playback mode is especially useful if you want to data-log a full throttle acceleration run.
