Hello, first off i'm new to this forum. Just purchased a 2004 F150, 2 weeks ago. It has the noturious throttle lag issue when accelerating from a roll. I know that there is/was a TSB to reprogram the PCM for the issue.

My question finally is does anyone know if this TSB (04-21-14) is still around? My ford dealer called after I scheduled the appointment and said that there system says the update is discontinued?

Is there a TSB that supersedes 04-21-14, or do they just not want to deal with me and my problem? I know some of you are going to say just get a tuner. And I will agree with all of you, with my experience in tuners for diesel trucks. But currently I can not let go of $400+. So again, any help will be appreciated.
