The DataMaxx Professional Kit is a must-have for any heads up racer. Protect your expensive investment by using a data logger that monitors every cylinder and pressure necessary to increase horsepower without damaging your engine. Data loggers have long had a stigma for not adding horsepower, and while just adding it doesn't, the information and knowledge you gain from it can be more valuable than any bolt-on part you could imagine. This specific kit is designed for the heads up racer that needs to monitor the motor closely. If you're pushing your engine trying to squeeze every ounce of horsepower out of it, you're walking a fine line of maximum performance and catastrophic failure. Having a data logger allows you to closely monitor your engine and realize when you're heading over that line, saving you thousands of dollars while still getting maximum performance. Comes with Engine RPM, Driveshaft RPM, Fuel psi, Oil psi, Accelerometer, Boost or Nitrous psi, 8 EGT's, Remote SD Module, Battery Voltage and 2 Switch Monitors
