thanks for uploading that. I tow a 12k 5th wheel and feel like the truck struggles more than it should with it....like really struggles. I pulled the tune to compare to yours but the only real difference I see that puzzles me is the boost correction table. My left colums are all 2.9 which seems odd. Any idea why it's like that? I was hoping the previous owner had put a fuel mileage tune on it or something and that would explain the struggle.
