I had lots of orange residue in the turbo and DP after running just one tank of Torco but I have also read it is really not a big issue.........
Not making the power I had hoped to see as well so switched to E30, had to drive 200 miles round trip to get it so picked up 22 gallons, had to buy the jugs, etc......and use my dually so it was a bit expensive but I figured I would just deal with it as we travel carry cans in the back of the truck.
Still not making the power I wanted, best was only around 231 HP and 258 ft lbs which is low for a Cyborg turbo but we were blowing out the spark above 6k RPM in the 30 degree or lower weather.
After 100+ tuning runs, trying Torco then E30, the Torco may of worked out after we figured out a few things, I decided to just go to the EFR which I had planned on doing before the first Cyborg, which was mine, was even heard of.
Now I am just waiting to get over a very nasty bug and get the car together and tuned on the EFR DHM turbo system, which I imagine will make all the power I need for road race track use and still be very street friendly.
I will just tune on 91 as that will be easy to get most anywhere, we are going full time RVing with the car in the trailer.
If not quite the power I want then will wait and see what happens in the 5th injector setup as I like that idea the best, no additives, no fuel blending, not much in extra hardware or weight and it will help clean the valves.
------------
All that said, if you go the Torco route get it tuned right and let us know how it goes, please, my car was never fully sorted out with it.
