I did a search and came up with some good info on dfco. Klugs SS and Atomic suggested similar settings for these tables, I tried it out on my truck and it would rev up and down while in dfco. I believe it was trying to activate/deactivate, any one else have good luck tuning this? Should I even mess with this for a little fuel economy?

 

Try adding some more timing, like 10 degrees instead of 5, while in DFCO.

 

Wtf mine reaches like 130mph revs up and then starts going again, what's this DFCO thing.?

 

dynamic fuel cutoff. It turns off the injectors when you let off the gas.

 

Thanks Atomic,I'll try it out.
