Anybody know where Shell URT advanced 110 unleaded race fuel can be purchased or ordered???? I have basically been told I can't run my nitrous setup without it, lund wont even build a tune for it unless it is a fuel that he trusts will keep the car from blowing up...Which is most the unleaded fuels VP 100, 105 Shell URT 100, 105 advanced at 110. I take it the other leaded fuels are oxygenated and it changes the stoich number enough to make the car run super lean. Which is fine, I would rather be told No then blow my car up because the tune was sold to make a quick buck....
Any help would be great thanks.
