When I go into sport mode and Manuel shift the radiator fan spins really loud, like a jet engine loud.
My car has bootmod3 stage 2 tune, catless, charge pipe, intake, intercooler
What is causing these issues

Coolant temp sensor would be a good place to start.. when the ECU cannot reliably determine coolant temps, or detects the temps trending higher without a plausible signal from the sensor, the default would be to assume worst case scenario ie an overheated engine, thus the high fan speed.
