scha0786 so I think we can put this thread to bed. It appears everyone's truck shifts early and lugs.

I just wanted to make sure mine wasn't having issues.

It seems if I'm heavy on the throttle or have a trailer hooked behind it actually shifts way better.

Regardless, it has to be way better than those 10 speed guys, slamming and searching all day long.

thekroog Mine shifts to 6th OD around 45MPH at about 1200RPM. It seems to lug that low, but Ford does that to maximize MPG.

I'm not sure what you are referring to. I tuned my 6.0 within two or three months after I bought it and never had an issue with the tunes I ran. I did do headgaskets at 185k miles, but there's been a lot of non-tuned trucks that didn't last that long. That truck is still going strong at around 275k miles now and still tuned with SPD.

I initially was not going to tune my 6.7, but I despise the EGR/SCR/DPF requirements and the problems that go along with them. Custom tuning is the only way to get around that.

However, you can also get emissions legal tunes and TCM only tunes. So you can keep the OEM tuning for the engine, if you prefer, and only change parameters (ie. shift points) for the transmission. My shift points are almost perfect. The upshifts are spot on, but I wouldn't mind if the downshifts were delayed a little.

'16 KRLB City Slicker Mine will shift into 6th between 45-50 MPH like the others have posted and lug it and downshift on a hill if it drops to 41-42 MPH

I think it just is what it is.

No, but it would be cool if Ford offered different tuning levels and shift points.

You can run emissions compliant PCM tunes along with a modified TCM tune or just run TCM tunes alone with the stock PCM tune.

The emissions compliant tunes are pretty good now. You still have to deal with the regens, DEF and the associated crap that come along with the SCR/DPF system, but you can enjoy a bump in performance too.

Warboar I just push the tow haul mode so it holds the gear a little longer. I got used to doing this in my RAM because it would shift way to early and then lug the motor to much.
