Try the Diablo. They’re about the best for that. Do a full tune up tooif we try i can get low 20 out of my wifes AWD charger (R/T version) but it is usually closer to 17
and on road trips i get 15 out of my 2500, probably closer to 12 around town
the 2500 is our family hauler, so that is the one id like to stretch a little
