Alright, I've finally found my 'kick' back. All because of one stupid thing. Yesterday dyno until no fuel..went to pump fuel again..dyno 2 more time...blardy hell!! the kick came back. The first dyno results indeed did show a flat spot on the chart.. after refuel, no more.. it's the stupid petrol! last time i pumped shell until some idiot decided to r&d with kerosene and petrol. Then i switched to projet(i always stick to 1 or 2 stations only). I think some smart alec also decided to do it with projet this time round. Yesterday i pumped petronas, ok already now.
