Just received my predator. Seems like alot of members swear by the 180* thermostat. Is this a necessity to get the full benefits of the tuner? I also have the hemi builder's guide to performance mods and it states that changing to a lower thermostat is a myth for performance and could be a problem with startup and codes if you live in a colder climate. I live in New York, and we definitely have cold winters and I don't want a problem. Diablosport states that it was tested on a stock car with great results, however; I would appreciate some input from my fellow charger owners. Thanks for the help.
