The dummy gauge on my car is possessed. Stock stuff the temp was always 1/2 way. With Koyo radiator and e-fans, driving around used to be at 1/2 way, and an 1/8" down. Now the dummy gauge is about 1/4" from the bottom, just within the "operating temp" brackets. If I rev the car or boost, the gauge flys to 1/2 way, then drops back down once I get off the gas.
Is my car running that cool suddenly, or is my water temp sensor shot?
