At WOT, the bike starts stammering and losing power around 4800rpms. It happenens with or without the auto-tuner engaged. When the tuner is engaged, it stays right at 12.8 AFR like commanded. It has a fresh fuel pump, and I keep the torque tube filters clean too. The only thing i can think of are new plugs and wires. What's the widest plug gap you guys run without running into issues? I'm using the factory recommended gap right now. It is a stock 100 with torque tubes and a bassani road rage.
