Similar TQ issue?

[f150Stang]

Hello all – I just got my custom tunes about two weeks ago and have not changed anything from what Bill programmed – previously ran canned tow tune for about 3 months with no issues at all (except for minor shudder on 1-2 shift not present in stock program or in the new 87 performance tune)

Anyhow, just took a trip to the Ford Carlisle show this weekend using the 87 performance tune – got to see the new Mustang, Raptor and Taurus…all very awesome! I noticed a shudder that felt like a miss for about 1-2 seconds a couple of times – for instance, while using cruise control on a back road at around 50mph, I would be going down a hill and when the hill started to level out and go back up hill, I would get the shudder – I believe this was in OD. On the bright side, I did get 19.5mpg including some town driving and A/C!

To let you know – 2006, 5.4, 3:55 gears. Any suggestions for things to adjust and what to adjust too? – is there anything I should monitor?
