Need advice on "Defueling Coolant"
I need some help here. When I am towing up a steep hill the engine sometime start to cut power because the temp starts to climb. I have a bullydog GT tuner and when I looked at it it said "defueling Coolant. The programmer is in tow mode (low power) but after coolant temp climbs past 210 degrees the programmer goes to no power (stock). It will still give some power but slows down to about 50-55 MPH. This did this while programmer was off also and even does this in tow mode. Anyone heard of this before and is it normal or do I need to have it looked at? Only happens when I tow.
