7.3 runs a bit poor... Shop says tuner?
Was hoping to get done feedback before getting a new tuner. I currently have a dp tuner f5 chip on my 2001 f250 with 160k miles with stock, 60hp tow, 80hp tow, 80hp Eco (city) and 120hp race. I had some turbo surge sometimes when the engine was cold as well as random jerking at 70mph with cruise.
Truck shows zero codes, injectors all are working properly and no compression issues. The mechanic told me it runs very poor in when it's cold except when it was set to stock mode. It also seems to slam into gear so I'm guessing my tranny is suffering a bit.
Any thoughts on whether a tuner chip not tuned well for my truck could be causing all my issues?
Any feedback would be great. This is also my first 7.3 and I bought it in December so I'm not quite sure how it should run.
Thanks in advance!
