TST's POWERMAX™3 with Remote with Digital Gauges for $899, allows the driver to have the same ten power levels as with the R35 remote, but has the added safety and convenience of built in digital pyrometer, boost and trans temp gauges. One of its biggest features is the monitoring and controlling of the exhaust gas temperatures (EGT's). It will automatically reduce TST's additional power and if necessary, go on to reducing stock power until the EGT's or Transmission temperature's are back to the user selected temperature. This feature could help prevent damage to the engine or automatic transmission caused by excessive temperatures. The user can also turn off the temperature control, for those who use their PowerMax units in competitions such as sled pulls and drag racing.
