Bad Idea?? Yes, the computer is looking for 195 to put the truck in closed loop. If you put in a 180 you constantly stay in open loop. Trucks that run cooler tstats will require a different/reprogrammed chip to compensate for the cooler temp. Also remember that the sender for the gauge is in the head and the one for the computer (the one that may be causing you issue) is in the intake.
