I thought I'd post an observation because it threw me for a loop. The Idle Underspeed Adders will only add spark up to the value in the High Octane (maybe Low?) Tables. I was working on getting the perfect lope at 700rpm and getting the throttle kracker to function properly with my extensively ported throttle body when I found the issue. A search didn't turn up anything, so I figured I'd put this out there for anyone else scratching their head.
