Last Wednesday Marlin Crawler finished installing their Dual Ultimate Crawler in my '01 Tundra. I have 4:56 gears so my stock crawl ratio was 33:1 but it's now 154:1 in low range and 60:1 in high range. When comparing apples to oranges (automatics to manual 4/5 speed) it would be 308:1 in low range.
