I have a question.......When running a delete tune without the DPF and EGR, which devices need to be continuously connected to the OBDII port if any? I'm only interested in a stock delete tune that doesn't need to plugged into the OBDII port. Does this exist? And who supports this and who doesn't?

 

I am using an SCT X4 with tune from tyrant loaded on it. No need to have anything constantly plugged in. I would expect a stock only with delete to be the same manner. From 7.3 days, I constantly monitored egts with the A-pillar gauges, after one drip with OBDII plug and forscan running on the phone, for what I was doing decided I wasn't going to worry about it. At the time it was the most load I see and running up the canyon is a pretty good climb. So I have it set and forget with the tow tune. I do find it interesting many indicate the 6.7 as being sluggish off the line, I am pretty sure this is all in the torque management side of things. If you disable traction and stability (at least to 20mph) by press and hold for 8 seconds, the things feels every bit as responsive as my tuned 7.3 off the line, only without the smoke show... I'd be a happy camper if there was a setting or tune we could change to permanently disable stability control, even more so if it could be selective with mykey. That would be slick
