My truck did the same thing. I had stock tubes for a not so stock truck. It would look at idle and sputter but run great when you have the throttle down.
If the throttle felt much more responsive and the engine seemed to have more power as you described, the rough idle is probably the timing being significantly advanced, which should also yield better fuel economy and lower EGTs. A bad camshaft sensor will completely stop the engine from being able to run at all.
Hey I also have a banks chip in my 7.3 and was meaning to get the hydra tuner was it hard to take out the banks tuner and what do I need exactly to take it out anything like new harness or something? I’m new to owning a diesel and mine came with the banks tuner and was noticing the same problems as you
My problem ended up being a faulty chip. I called banks and they said that is a common issue for older tuners. I didn't completely take it out when I switched to the hydra. Just unplugged all the sensors except for the thermal probe in the header so I could see my egt. Install of the hydra was straight forward and it's working much better now. No idle issues and plenty of power.
Do you have the same six gun as the video shows? I just bought a truck with that same tuner and the turbo and the fuel connections were disconnected. I’m wondering if there is a reason.
After talking to the Banks customer service we figued out it was the Banks chip that was malfuntioning. I switched it over to a Hydra tuner and haven't looked back.
That is a lot of mud! We have a trail that has the first turn called GateKeeper as well but yours looks a little more challenging. Ours is more big boulders. Another great upload!
Nice rig!! That first big hill looked so hard to climb with the water running down the middle of it. Awesome trail! Just found your channel and looking forward to watching more
