Pulsating on acceleration

[Boadie]

My buddies Superduty 6.0 2005 is pulsing when accelerating generally at speed of about 30 to 50 mph. We already been to Ford they reflashed it and stated they did not find anything. Any ideas?

what kind of pulsing ? like VROOOM vroom VROOOM vroom

and the yellow is nice and all marine but its awfully hard to read.

Yes! we were just having this discussion.
My coworker's 06 is having the same problem. It seems to be pulsing 50 to 75 RPM. Is more pronounced cold. I can hear the pulsing and you can see it in the tach.

That is correct its is only noticed during the cold weather he actually had the problem last winter as well, he was flashed and stated it was fixed that time. Not so this time. I'll mention the EBP Ill let you know. Thanks guys!

Let me know if there are more ideas.
