BD 40420

[prairiedawg]

Has anyone tried out the BD 40420 on their Ford 6.7? Just curious on how well it works or if there are issues. I don't want to delete anything off the truck at this time.

No one really likes the Bully dog. It's canned tunes, no trans tuning, go h&s for for good custom tunes with trans tuning. You even have the option of getting KEMs tuning, they have made almost 500rwhp with nothing deleted.

Could not have put it better. Bullydog and banks are crap. Only way to go is H&S

Prairie, I have done MONTHS of research on tuners and it does appear that H&S is the way to go as the others have stated.

Another vote for H&S. The tunes are much better plus it has the option of deleting your DPF in the future if you ever feel the need. You cant go wrong with H&S.

HaHa...Sgt93, have you finally decided on H&S? I know that you were debating between H&S and Spartan. Thanks for all of the information that you post on these forums, it helps a lot. What made you decide H&S over Spartan?

Is there any chance you can get the KEM tunes in a xrt pro? Or do you need the sd card based mini or max? I run the h&s stuff on my dodge, love it.

Yes the KEM tunes are made to work in the H&S monitors.

Kem Tunes better than H&S?
