One very important thing to remember with 7.3 programmers/chips (I can call it that, that is how chip got started, because it is a chip that plugs in) is that when you plug it into the ECM, the truck needs some time to learn it and get used to it. If you program a truck with a Superchip, it might not be all that impressive at first. Leave it on there and drive it. The more it runs, and get turned on and off, the more it will learn and adapt. After some time, the trans will love that Superchip, it will shift perfect and haul the mail for what it is.
With a flip chip like the TS, every single time you switch it, the truck gets confused. That is why they destroy transmissions, it never gets used to the settings. Different power levels have different settings in the trans. If you keep flipping it around (and you inevitably will) the trans will slam gears and get lost between gears and just be unhappy. It will also throw the check engine light constantly, and sometimes even go into limp mode. I was told this straight from TS long ago, and have seen all of it happen just as they warned it would.
This is based on my experience 6-11 years ago so maybe the TS 6 position has improved, but I don't see any way around this, regardless of who tunes it. Unless all levels have the same trans settings, and maybe they do now, but they didn't before.
I have owned 2 7.3's, I have 2 brothers that have both had 2 7.3's, and my dad has had 2. That is 8 of them in my immediate family, every single one has had some sort of programmer/chip/module. I have been out of the 7.3 game for a long time now, and spend very little time in the 7.3 forum. That said I don't think this information has been covered much, but I could be wrong. Sorry for the long read, but I think its time something useful was posted, not just get this or get that with no info behind it, by people that have likely only tried 1 or 2 different brands. It's easy to say the TS is great, when you haven't tried anything else. Heck I thought it was great power wise until my one brother had it on his truck set to highest setting, lined up to my other brother with the Superchip set on highest setting, Superchip truck flat embarrassed the TS. Both F350, both 2003 model, same truck. Yes I am talking off the shelf tunes, all there was back then. TS smoked like a train and Superchip ran almost clean as stock. TS truck also had intake and 5 inch, Superchip had stock intake, stock paper filter, gutted stock exhaust.
I am not trying to bash TS. Ok rant over, take it however you like.
