My 96 cobra has a C&R radiator and 180 thermostat. the low speed comes on right before the "M" and the high speed dont come on til right before the "L". to me that seems really high. i want to turn the fans on earlier. I called hypertech and superchips and they both told me that their tuners only control the low speed. Is this right? anybody used a tuner for this? if you tune the low speed to turn on at 180 like they advertise does the high speed come on at an earlier schedule as well? please help, im at wits end.
