Depends on the Edge tune / tuner. Bill from PHP used to work for EDGE from 04-07 and did their tunes. He is still subcontracted to them however I don’t know how much programming he does there anymore.
If you do have an older EDGE programmer they had a problem with the OBD2 cables where they would fail programming killing the PCMs. This was a cable issue and not an issue with the tuners or tunes themselves. FYI.
I think I’m sold on PHP.
