just remember that Torco, while it works well, contains MMT, which turns into an orange-colored fouling in your exhaust system, which can over time, clog your 02 sensors, and if you have them, catalysts.

They almost all have MMT. It's the "active ingredient" in the NOS stuff, too.
It does color things orange, but who knows how long it takes to foul things. Ash has apparently be running it in every single tank for 25,000 miles.
People run lead additive, too. Turns everything chalky white. That, apparently, is quite bad for O2 sensors though and murder for cats.

No problems at all. I had a TXS tuner in my car for 10-12k with the bosch lSU sensor mounted in the stream 2" after the turbo. When I pulled it out it had an orange film on it that was thin enough to wipe off with your finger. I managed to pull out the front left spark plug a month ago (about 25-28k of torco through it) and it was about the same. I haven't had any related CEL's or cold start probs. All in all I'm very impressed. I dont want to make any promises or pretend to be a chemical genius... All I have is the info I've collected personally. Great stuff. I will continue to use it every tank for the life of this engine. 63,000 and counting...
This would be a great time to chime in if you want some. I'll be at big dogs tomorrow, but not till late.
