I can be going down a slight long incline just cruising at maybe 60 65 and you know the engine is just not relaxed and the MDS won't kick in at other places going up a slight incline no problem the MDS just stays engaged.
Good point on the road surface, I have noticed that too.
Way to be observant
I think we should all buy those $69 chips that give us 70 more HP and 7 more MPG and all would be grand with the world lol
