I have a 2008 Superduty 4x4 6.4 manual 6-speed and installed the 1808 flashpaq and it works really well other than the truck surges at steady rpm.

Glad 2 have U join us here at FTS.

Sounds like you have a sweet truck!! Just a suggestion, you may want to contact SuperChips about your surging issue. Because the truck is so new, they should know about it so they can look at their code to see if it is their issue. If your truck didn't do it B4 you added it, I'd guess they have something to fix.

Did you call Superchips?

I hear that Ford has a memory cache that tells the technician "IF" a chip has ever been hooked up. And it can't be cleared. Is this so? Could be bad for warranty reasons. I don't know.
