Well, the problem with running boost on a Spoon engine isn't the high-revving, but rather the high compression and agressive cam profile. Spoon specializes in agressive N/A tuning, so slapping a turbo on one of their engines isn't exactly the best thing to do. The high compression means you'll be more likely to detonate,a dn the overlap on the cams is somewhat counterproductive when boosting. If you run a Spoon ECM program, the problem is compounded by an aggressive ignition map and insufficient fueling for boost.
