Volvo do not claim any fuel economy improvement on their website... https://www.volvocars.com/en-ca/shop...r-optimization
I think you are basing this on assumption? I never claimed they said that anyway so ........ ?

Anyway from the cars I have had mapped, I have always had increased mpg, non of the maps claimed they would increase mpg, they just did as I got them for the increased gains.
