Is there any benefit to Diablo or Excalliber programmers?

without the programmer, you cant retune the engine for your mods. sure the tuners and the sources you listed all have DTC information, but the tuners allow you to fix the problem thru your tune. you can adjust the parameters needed.

I have access to ALLDATA, but it's not going to help you
