I believe I said you just can't put it in your car and run it and that there are drawbacks.
It works great for me and I daily a car with it (4 1/2 years so far). The car has a modified fuel system to support it and a tune to make it work.
I understand that no one tuning the ST or any focus for that matter it seems, is using it. That's all I started this thread to find out, not to get in a pissing match with people who don't know how to use it or have failed at it.
