I have to admit, she behaves pretty good when I get her up there, no shakin', no heatin' up, pretty smooth for a '93 with 130k. I have most of my "speed competitions" on the freeway, so I have my timing "turned" the other way, retarded a few degrees, it really helps out on the top end. The few that I get involved in off the freeway, I just make sure I am using the upper rpm range, about 3-5k rpm.
