He did say that on the weekend he noticed that when the dual cooling fans were on, the fuel pressure would jump around, and drop. The regulator is mounted on the front of the engine, and the fan on that side blows hot air right on it. When he cooled the car down between rounds more, so the fans didn't come on during a run, or in the staging lanes, the pressure stayed solid. So he is moving the regulator to the fender, and wrapping all the fuel lines under the hood with foam pipe insulation. But, the performance didn't change even when the pressure was moving around.
