You can do it on your own if you are able to use tunerpro with your bin. Below is goat rope garage and he shows you how to setup your tune for a bigger cam. He uses HP tuners but honestly I have went...

So I have a question about COS he mentioned in the post below. I am trying to run my 2000 5.3L in speed density and been running into a road block. I seen he had XDF for two custom operating systems...

Thank you LRT! Also would your XDF work with my 09354896 ECU? I have downloaded my bin file and when I open it in tuner pro, the values are not right. I used the 512 checksum and the 12202088 XDF.

Thank you!!! Also would it be possible to get these XDFs complied into a ZIP file?

*Edit* Would these XDFs work with a 4896 ECU? Its pretty much the same as a 0411
