I still have the stock thermostat and have not made a decision one way or the other, I'm really happy with my car currently, however, I am not opposed to the 160 if there is a benefit, but would have to change the tune and I am not sure if the tune with the fan changes will work on my older SCT tuner and I don't think it would be worth the extra money if I have to buy a new tuner just to turn the fans on earlier...and when I last checked LMS said there wasn't any updates for the tune I'm running....
