I hear ya!!! I went from a 3.73 with the 4-spd to 4.56 with the 5-spd. I figured if I'm going to have that much overdrive I'm going to make it worth it. Cruise RPM dropped from 3500 or so down to less than 3000. 60' time dropped real nice and are consistent too thanks to more gear letting me run taller slicks(28' vs 26') without bogging off the line. Low 1.6 are the norm and was pulling 1.53 when the slicks were new. I wish I had as much good things to say about the top end charge.
