OK Let me try to explain the best I can, the car runs great under normal driving but if I do a 1st through 3rd pull as soon as I power shift into 3rd the car seems to loose power almost like no boost, so I started watching the 2 boost gauges that I have and they are reading vacuum but only 1 maybe 2#s of boost under load and this is constant,so question is could my boost bypass actuator be bad and not closing or staying partially open when I go to 3rd , or could it be in the tune and the tune is telling the BPA to open under load. I have checked all the lines and even had a vacuum/pressure pump on the lines and nothing, my gauges will even show boost(with the pump only). So please help I am completely lost. Where should I start. I called Ford and a new BPA is 180. I am not looking to just throw parts at it.
