fan kick on/off temp - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a dual speed single fan that seems to run all the time. Temp seems to stay right at 200 even when going 80mph.

The tune has the activation temps as follows?
Fan 1 on 195 off 185 - low speed
fan 2 on 215 off 205 - high speed

if the temp is always 200, fans are alway on even on the freeway.

Should I have a reflash done with higher temps? Change thermostat for a lower temp? The one in there is a oem temp. Or maybe the 6 cylinder radiator isn't cutting it.
