Massmike, I noticed you mentioned when cruising, your in the 2000-3000 rpm range. My experience with my 1980 CIS that if I do run under 2500 rpms I get a similar surging feel. Porsche reccomends 3000-4000 rpms for normal city driving and when cruising at higher speeds 3000-3500 is ok in higher gears
A porsche engineer told me many years ago to keep rpms above 2800 minimum.
Hope this helps
