About the only time I see that might be needed is if you’re running some huge hp Los of timing advance advance fuel guzzling high rpm turbo monster where temps need to be managed more…. Or you have some big hp tuner thTs programmed to dump fuel that’s gonna raise under hood temps. For a pretty much a street driven truck that isn’t tuned or heavily modified a low temp stat it’s not needed. If hire running hot you have cooling issues that a low temp t stat will simply just mask.I agree and that's exactly my understanding. When do you think a lower thermostat is a good idea? is it in extremely hot, desert like environments like Arizona?
