Power loss
2004 F-250 super duty 6.0L with 31,000 miles and installed SCT milage tuner suddenly won't maintain speed. I can accelerate but the response lags. Main thing is a huge power loss and you can't maintain speed at any constant pedal pressure.
Very odd slow idle when stopped.
Any suggestions on what to start looking at??
Thanks

If this started happening right after you installed your SCT tuner, it would stand to reason that the tuner may be the cause of your woes.
If that's not it, I'd look at your fuel filters. Have they ever been changed?
