Message	See profile for full mod list. We made the following fuel mapping changes on my AFC +2% 3,000-4,000 +5% 4,000-6,000 +4% 6,000-7,000 Which produced a A/F curve that goes from 14/1 at 2,750-3,750, 13/1 at 3,750-5,000 and 12/1 at 5,000-7,000 rpm. These were done last summer on the dyno, while member timz listened to the engine with his headphones. Not even a hint of detonation. With this set-up I hit 429.9 rwhp/464.7 rwt.
