I have a problem. When I had the car dynoed The Aviator fuel pump was at 98% duty cycle at only 382 rwhp. I thought the were go for at least 450.

I also have the occasional stall when coming to a quick stop. A jerky feeling a low rpm when coasting and off throttle but not all the time just most. Also tip in ping once in a while.

I have had the car tuned by 3 different qualified tuners.
Still the same problem. The only time it has cleared up is when I first installed the Aviator fp.

Do you think I have a fuel pump starting to go?

Certainly sounds like a bad pump or a bad fuel rail regulator. I have a Focus pump and it works fine.

Did you data log your FP duty cycle. Thanks for responding? I 'm considering the SVT focus pump this time.
