I posted this in another thread, too, but I replace my R/R with Rick's today. Here are my results so far:
RPM ------ Stock R/R -- Rick's R/R
1,050 ------ 12.4 ------ 13.9-14.6
1,500 ------ 14.4 ------ 14.6
2,000 ------ 14.1 ------ 14.8
3,000 ------ 13.8 ------ 14.8
3,500 ------ 13.8 ------ 14.8
4,000 ------ 14.0 ------ 14.8
The swing at idle is a little odd but I'm not worried about it. It was an easy upgrade, but sucked having to cut the cable for the factory R/R.
