IMHO " ECO mode " does change the MAP somewhat ….. If I have MY OEM 2014 RT in " eco " mode, it isn't as responsive ( and this has nothing to do with the shift lights )….. I think it does this via a slight RETARDING of the spark …. how this might relate to an ECU Flash I won't speculate on …. maybe Steve can enlighten us ...……………...Mike
