[QUOTE=tjlazer;3607284]I think it's IAT as I had been monitoring my air intake temps. It would spike when sitting at a red light, heat soak has to be it. I seem to have issues when I get to 190-200. Very bad lag on low rpm fake offs

Please excuse my ignorance. I'm guessing IAT is Intake Air Temperature. From my experience even if it's very hot outside with temperatures past 40 Celcius / 104 Fahrenheit as long as my oil temperature shows under 90 Celsius / 194 Fahrenheit it won't lag at all.

Could this mean that under heavy heat soak/ high under hood temperatures our engines are getting pre ignition/pinging and the knock sensors are retarding the ignition therefore we are losing low end power?

Did you find a solution for this issue?
