First tuning, hopefully someone has already made a file

[Rock.black.sheep]

I'v been working on this car for 13 years, I'v been through 5 engines, and 4 transmissions over the years. I finally bit the bullet, and went to an LS against my will. It's a 6.0 that's completely stock, I used the NNBS intake manifold and EV6 injectors. The 4l80E has been rebuilt, so I know there's nothing wrong with it. The car has a full float 9" in the rear, UMI control arms and Viking coil overs all around. 275/40ZR17's on the front, and 275/55ZR17's on the rear.

I had someone "tune" it already, he didn't do it correctly and refused to fix it. So, I sent my ECU to someone else, and he didn't do as I asked. I'm on my own now, so I had to turn to the internet for some help. I have PCM hammer and tuner pro, but I'm still trying to learn all of this. I'm really tired of having a car that I'v invested thousands of dollars in just sitting in my garage undrivable.

Does anyone have a file I can steal?
