I got my Hypertech ThemoMaster chip today and it recommends a 160* stat. I have a 180* in now, should I go with the 160 or can I stick with my 180. l live in Georgia, so it gets hot in the summer, thats why I ran the 180 intstead of the 160 in the first place. Is the chip programmed for a 160 or just a cooler than stock stat? What should I do?
Definetly go for the 160 with the 4.3 and since you live in GA! The 4.3s run hotter than the 2.8s in my experience. I run 160s in both my trucks in OHIO!
If thats what its designed for, you'd better use it.
