Not true. At least from my observations. Switching over to the lumpy cam in My DC2 doesn't really use that any more fuel. Obviously, you use more fuel with revs, but the VTEC cam switch point doesn't seem to be a magic point where it starts chewing more fuel to me. At 7000 it seems to chew about as much fuel as driving at 3500rpm * 2. The fuel maps are pretty close to stoic.
You can't run close to 14.7, not at full throttle or heavy load. Probably about 13:1 for a tuned NA, compared to a stock ECU at 10.5-11.5:1.
