Like Q said , its depending on how you want to drive 99% of the time.... in my case I like to drive longer distances at higher speeds , usually I cruise at 85-90 or more , and like the 'passing ability'...I`m very happy w my power band...kicks down at 60-65,and just goes!i`m at 90 from 65 in no time...and I like the 14 mpg at 70....90 mph = 3000 rpms for me,60 mph = 2000 rpms... thanks again Q, for the help!
