Get that AKra map NOW mate, dont thrash it until you do, you risk valve damage from overheating!
The Leos make it run lean below 4krpm even WITH Akra map.
Also, when they do valve clearances they do not check the valves themselves so you will not get a report on any such damage. It's only shims under the buckets at the end of the valve stems.
BTW SD idle is about 1500rpm but dont trust your rev counter to indicate it that accurately. Your dealer can check it at service...they will also NOT balance throttle bodies unless you ask them to, and some wont do it even then!
