Issue my fans are constantly fully on, both signals fan #1 and #2 are coming directly from ecu and always grounded. Looking for a local SO CAL tuner to help me out with that.
Rest of the tune seems to be good.

LS6? So P59 or P01 controlller? They have no provisions for PWM fan control. That feature did not come until E40 controller on 2005 C6 Corvette. Subsequent controllers (E38, E67, E92, etc) have selectable outputs for fan drivers (descrete, PWM).
You'll need an aftermarket PWM fan controller to do what you are asking.
