M8 running lean on top end with original 07' programing?

[White Rad]

pulled a plug after a few good climbs and they were on the white side....anyone else notice their sled running a little lean on the top end with the original 2007 programing? Is there an 09' re-flash that is better than the 08' one?

thanks
