I just installed my new Diablo chip about a week ago. Unfortunately there was something wrong with it, and it wouldnt work. So I have left it in the stock mode, because according to Diablo with it turned to this mode the ECU does it even know it is there, I was planning on taking it out at a later date because they were going to RMA it for me. What was happening was this. My temp gauge would hit half and them ping out around 3/4 to max temp everytime I stopped at a light. I have now removed the chip, and it still did it. My car usually runs under half. So I had Ford replace the thermostat and both ECU and CTS sensors under the hood, flush and clean out the rad. Now the car doesnt spike but it constantly runs just over half. Anyone have any ideas what the issue maybe? is my waterpump on the way out?
