Don't have a Ford but I had a Bully dog tuner when I bought a used 2007 Duramax so I said great and tried it on tow mode on my maiden Voyage with my 5er I found out REAL QUICK going up my first stepper grade this thing SUCKS for towing my EGT's went too high and so did the tranny temps so I turned it back to Stock mode and all good again now I do not even use the tuner except for info Canned tuners suck IMO for towing
I agree, but I think power-hungry Diesel has a pretty good set up, I really like the hydra chip, they have a lot of choices and they have many tunes for a modified valve body. I went with the lowest horsepower version and I’ve been running it for years and it has always worked good until now, I’m still not sure what happened but I will be investigating, hopefully like Some said maybe it’s just a sending unit problem, I recently redid all the wiring harness is under the valve covers and also the ECB, as well as changed out the ECB of course. The problem is where I live, I don’t think there are any reputable transmission people and going down to John Wood’s in California to me is like going deep into enemy territory
