I don't think the TS tunes are even as good as the superchips 1705 I had before, shifting stratagies SUCK,,,IMO,, sent my TS to twildman for a reburn, I'll let you know how that works out.
for the 7.3 everyone except DP Tuner uses what is often called a TS chip. The programming that will come one one from ebay or TS performance is old, outdated and while better than stock much better programming exists.
All of the following companies sell TS style chips many have their own company logo on the chips also.
Total Diesel Performance
Diesel Innovations
Bully Dog (some older ones out there)
Diesel Manor
Swamps Diesel Performance
Beans Diesel Performance
Power Hungry Performance
