Not Ranked
Not to get too off-topic, but it should be mentioned that displacement can really impact the "hotness" of a cam. Just as a big cam can decrease the effective compression ratio, a big engine can "tame" a lumpy cam. I think the OP was a small block...so a hot cam in a 347 may be a grocery getter in a 496. But my self learning comments stand. In self learning, my ECU chased VE numbers to hell and back, even when I minimized allowable %correction at any given time. I do think the quality of low rpm low load vacuum signal is very important to these systems and I do know my vacuum isn't the cleanest or strongest in the world, again because of my cam. However, careful dyno tuning can and does work wonders.
