Instead of starting another thread i will use this one ! Will a 180 deg thermostat cause my truck to not build enough heat in the motor to make power or does it need a 195 ? I did swap a 5.2 in place of the 5.9 but also did 4.56s but kept the 5.9 pcm ?

180* tstat won't hurt anything unless you are in a cold climate.
Keeping the 5.9 pcm will most likely make the engine run rich, better check your O2 sensor readings. Running too rich will dilute the engine oil, clog the cat, and hurt fuel economy.
