For out of the box performance TS makes a great chip. I was running a TS chip until I needed custom tuning for my injectors. Its up to you if you want more in depth details I will gladly help you out. The last three were a joke compared to the other seven and I wouldn't reccommend putting them on a diesel powered trashcan. The old Bullydog tended to run a little hot EGT wise. I will list them from best to worst as my opinion.

Having two of them didn't cause the mail it and hurry up and wait hassle.I have compared a Superchips Tuner, Diablosport Delta Chip, Diablosport Predator, TS Performance 6 pos., Bullydog chip, Hypermax, Edge, Banks, Western Diesel, and a BD X power on our 7.3L powerstrokes. I am on the hunt for another something to drive, and if it winds up being a 7.3 again will use a TS style on it also. Only advantage i saw was emailing tunes if trying to iron out problems. I just preferred the old style switch, thought it looked cleaner as well. Ive come across a few threads on the multiple sites along the same lines but if recollection serves me right want to say it was all the way files were written as well, not a hydra problem, you'd think everyone wrote ( format)them the same way though. I didnt have any PHP tunes on it but they were moree than happy to help when i had questions after first getting it. I think it was the way the files were written and that's what the tuner told me as well when i asked why it threw multiple CEL for a few seconds as well as an idle stumble then would be fine with no lights, wont go into the who's and all but it stumbled for sure with multiple tuners stuff when going from one tuners to the next. It was ok I'm not bashing it by any means.
