Switched to a single 375ml nozzle tonight and noticed a big difference. The car is definitely much quicker. I only drove 7 miles so will post more tomorrow but the tire broke traction in 3rd at a much higher rpm where it never used to with revs that high. Could be because my tires were still cold but don't think so. It was much more violent of a traction loss than usual. I alsohave some confirmation on it being the nozzle as GIACuser experienced the same thing when he went to a bigger nozzle. I only lowered my start setting to 6 psi from 7psi full at 12 still.
