I have recently bought a Trinity and loaded the 91 tune. Since then, there are times when I have turned the car off that I have heard what sounds like the fan running down. Based on what I have read doing searches on this, some say the 91 tune lowers the fan settings a bit from stock and is already set up for a 180 thermostat. I have a jet 180 coming. So, will I be o.k. just putting it in and going or will I need to adjust the fans further? If so, what do they need to be set at for the Jet 180? I will say, I do not want the fans to be running all the time as I do not want to risk wearing them out.
