Question about rough running after customizing the tune

[ticopowell]

I dont know if I just am not doing it right, but when i try to customize a tune I can go input everything, the WOT adjustment, tire size, etc... but when i start my truck after the new program is installed the engine starts, but runs really really rough and then dies. I have tried it twice and each time the same thing happened. As soon as i change it back to stock or to one of Bill's tunes it goes back to normal.
Am I doing something wrong? or is there something wrong with the programmer?
I honestly hope that it is just me so I dont have to bother Bill or Corey too much. anyone know? thanks
and just on a side note, I ordered my Class Ring this week , I dont know how much anyone really knows about that on here, but It is a big deal for a cadet .
