I can almost bet right now that the reason you are running low power is because of your fuel pump. Your car is running rich and you have nothing to bring the fuel down. The coolant sensor wont cause the loss in power that you are currently experiencing. The mods that you have, there is no need to upgrade the fuel pump...AT ALL. This is the perfect case of "adding more mods = more power" nonsense. Anyhow, slap the stop fuel pump on and try to dyno again. With the KA24DE and your mods, you should see about 140whp. Its funny because the people who have been on the mustang dynos, then come here usually get lower numbers than the mustang dynos. I have never seen one read lower then our dynojet.

Look at your AFR chart. Its even rich for turbo application...it is totally robbing you of power on the NA motor. You should be around 14.0, 14.3 AFR. Youll see big gains over what you have now.
