Manage to meet bernard on 25th morning 10am ,after 40 mins Bernard come down with 2 maps,
1.1st map loaded performance slightly better than stock,
2. 2nd map slightly better than first one,i ask him whether can do better in low rpm range or not,he said if you have time i can try until you satisfied :top::top: .
3. Bernard takes another 30 mins come with the 3rd map ,this time the low rpm 1-3k rpm really feel good improvement,more torque ,over all i am happy with this map.ask him can try the 4th map or not ,still the words if you have time i can try until you satisfied :top::top: .
4.1pm try the 4th map,i decide drive the 3rd map home.
Thanks to all sifu ,especially thanks to Realred78.
