Same thing happened to me, had the pc3 hooked to the plug on the left side of the cylinder head, it goes to the brown one under the fuel rail. Fixed mine, also if its plugged up wrong the pc3 wont show any green bars when running or key on.

Mr 12 is great gas but I have to say I think you should not put it in without a tune, its oxygenated and the bike will need to be richened up, if you just pour it in your are running a risk, Ive had that stuff detonate on a tuned motor and tear stuff up, if you want to have a safer setup run vp import, I switched to it and my bikes runs faster than it did on mr 12,

also on your fuel leak issue, are you sure it is not the oring on the injector, if you leave racefuel in them it will kill the orings and kill your fuel pump, which if that happens when you start with mr 12 let me know cause I have three spare pumps laying around.
