It was 84 out. Humidity was 61% DA was 2948 but you think that would make it run 1.5 seconds slower and kill the MPH like that? Ran good 1&2 60' was 1.92 which isn't that bad. On the high end just fell on its face. I was racing a wrx had him to the 1/8 then he passed me like I was standing still. That's why I think the tune maybe no good. Shouldn't the x5m pull hard on the high end too?
