1987 Ford Mustang 5.0 mileage: 129,000.I have an 87 Mustang 5.0 that I race at the track. Last week it ran a 14.80 on the 1/4 mile. The car has been having a problem; it feels like its not getting enough fuel. It starts to jerk while I am driving as if it wants to turn off. When I race it some times, it backfires as if it is not getting enough fuel.I put a new fuel regulator on it and a 155 LPH after market fuel pump. Can you please help me with this problem?

Check fuel pump pressure and volume delivery. You may want to consider installing a fuel pressure gauge permanently and also installing larger fuel lines.
