Wow I wish I got those sort of K's per tank or km/100k. With filling up my tank I would be lucky to get 400km's. I have a ke70 with a 5k running 32/36, extractors, 2 inch zorst with lol sports muffler.
Just had the car dyno'd and carbie rejected, I some how seemed to be getting more K's/100 before this though??? And no it wasn't running lean.
