Finally broken in during the weekend and i was very happy with it. I use cyrul method and add some more castro in the 25% fuel as mention from jp itself and i found that the engine is little unstable with the rpm especially at the last two tank of the whole process! Temps were in 195-200 after 10 tanks and i start to run it on the track for another tank and seems like the engine sometimes rev up quickly and slow down to the point that the car barely move with full throttle. Any ideal?
