Any updates on the dfco settings you changed?

Mine only seems to do it in 8th gear at around 1100-1200 rpm during coast. Iv also seen/heard it surge at around 3k rpm. Except when it surges at that rpm it’s dropping several hundred rpm and then...

I have the same issue. Mine is cam swapped and thought that might be the issue. Going to pick up a dongle soon and log it. What rpm does yours do it at and what gear is it in?

I seen earlier where someone said to just upload the factory challenger 3.6 tune into the 3.6 of a different platform and it would put you at 305HP. Might could look into that.

Thought about just asking Jeremy? He’s a pretty nice guy and might would tell you if you asked nicely.
