My 07 GT has recently started having an issue to where when my vehicle is warm it’s starts bogging down. I recently switched the tune from my SCT from performance to race. Ever since the change, it seemed to have this problem. I returned the vehicle to stock and it’s still having the issue. The car will operate normally with 0 issues until the vehicle warms up. To give an example I can be at a stop and when I go to take off the car will act like it’s not getting enough fuel. I will have the pedal to the floor and it moves very slowly until it kicks in and driving normally. Even in neutral when I rev it will act the same way. I have recently changed the fuel filter, fuel pump and the fuel pressure regulator..thinking that was the issue. Has anyone ever had this problem or can provide any help to fix this issue?. When the computer is attached to the vehicle it shows 0 codes as well.
