I'm baffled I have a 06 5.9. That I am trying to use the calculator. That BAMOFO wrote. The directions are simple basically copy and paste your values into chart. Done that several times and no success. I read somewhere that the calculator wont work on the 06-07. The description says it will. I will attach my tune. Could someone please try to use the calculator with my tune. And let me know if it works. Or what I maybe doing wrong. Thanks
