    In performance mode, the Big G raises your rear wheel HP to 140 HP and 250 lbs.ft. or torque safely and reliably, without raising your EGTs to dangerous levels.
    With the Big G In-Cab Monitor, you can view over 20 different gauge displays, including turbo boost pressure, water temperature, air inlet temperature, engine RPM, MPH, horsepower and torque, voltage, and barometric pressure.
    Should EGTs creep up too close to dangerous levels, the Big G will automatically defuel. The Granatelli Big G can also display and clear Diagnostic Trouble Codes. And with an easy-to-use, one button display, you'll never have to take your eyes off the road to operate the Big G.
