With a t61 you should be able to push it somewhat. I imagine low 20's, but that's a pure guess. I am doing the same thing with my car, only 100 oct and a 68mm turbo. The only fuel mod will be the PHR fuel dampener bypass line. Cheap investment for maxing out the stock fuel. Which gas do you mean? C16, Q16, VP import, etc?

if i drop my boost to 1.4 bar its perfect 11.7 - 11.9

Well, your running a turbo that flows way more than a precision or turbonetics t61. So, thats a factor. Then, every car/fuel system is different. Take two of the same stock fuel set-ups, and one will run out of fuel before the other.
