Just got one of these last week. After around 1L of really slow run-in (mine is a pre run-in model so i don't think it need a lot of run in here, and the engine is nice and smooth after the first L anyway). So I start to lean the LSN to see what this thing can do.... And Holy cow.... with both the LSN and HSN still on the rich side this thing pulls like a train!!!!!!! Think it have way more low end than my IDM evo 4 and the high end is just a bit more than my PTS. But remember this is a new engine with only 1L through it and running at only 80-90 degree!!!! Think I better lean it a bit more to get it to around 100-110......
