Yes, Johnathan at Swamps has been providing me with tuning since I threw my hands up with the current offerings many years ago when watching most people tuning these trucks at the time was about like watching the monkeys throwing sh#t at each other at the zoo.
I was about to buy the software myself when I decided to start working with them on some tuning. With no emulator it was the old lets try this and that, go out and drive (4 at a time) and come back with something like, little less tip in, the fuel feed is a little sluggish or too much, whatever. Then reburn, and do it all over again till you got something that drove right. Something you would have expected that most of the other tuning would have driven like to begin with.
This was years ago though, back in the days of jacking the crap out of the EOT table and telling people that their injectors were "rattling".......
I don't think some people really know just how far tuning has come on the 7.3 in just the last, say, 4 years.
Now there are multiple places that can do live tuning (with or without the emulator) as well as live cylinder pressure testing to produce that tuning.
I don't believe that Johnathan has nearly the same level of extensive tuning for all codes and such just sitting on file, but as far as sitting down with a truck and getting it running properly, and happily, that's something he can nail.
If you happen to run a DAC3 (my PCM code of choice) you would have no problem finding programs at Swamps
