MMT is definately not going to do it here, it has no effect once your base stock RON is over 110.
Looking at the layer of soot in my brand new tail pipe from one trip to Nelson Ledges I can't believe my cat can have much chance of working anyway, so if you're serious about speed lose the kitty, keep a few O2 sensors in stock, and run C16!

But if Torco is the cheapest it's probably not a bad way of goosing your octane as a safety factor. Nothing's going to beat real race gas for consistent, safe performance, and even at Mid-Ohio GT100 is $5.25/gal and leaded 112 isn't much more.

When you run high levels of aromatics (like toluene) and oxygenates (alcohols and ethers) the vapor pressure profile gets all screwed up. Though that's less of a problem for fuel injection you may still wind up needing a 1500rpm idle!

Question for the guys using Torco, what psi are you guys running? Is it safe to raise boost to about 23-24 psi with this stuff? If you were to run race gas, you can crank the boost up right? So can you crank up the boost with Torco? I'm currently running Torco too but only at 22 psi settling down to 20-21 psi. I'm temped to crank it up just a bit. My car was tuned for 11.0 a/f @ WOT.

I'm a definite believer in torco as well. Take a look at my post from December. Torco is the only octane booster that I've seen independently tested...
