The tune is setup to pull timing slowly after 8psi. when it reachs 16psi its pulling all of it out and goin into the negatives to save the poor pistons. ive got an extra tank than whats in this picture but you get the idea 3 gallons doesnt really last long towing a heavy load with all 3 of them nozzles. i run 93 oct and tuned for it.. then slowly added the methanol till i got to 100%.. i started out using -20* windsheild washer fluid and its ~33% methanol. ill throw in pure methanol for the track and use -20* WWF for towing since it helps keep the IATs cool. - - - Updated - - - Ive also got 91# injectors and they are almost maxed out on high boost haha.. time to go bigger.
