By drive agressively, I assume you mean when he stomps it, and goes for a lot of boost. Does the engine feel like it's misfiring at high boost?
It could be a weak DI (direct ignition) cassette, but the cheaper thing to try is to check the spark plugs. If the plugs are worn and the gap is too big, the spark won't jump under high boost conditions. Pull the spark plugs and check the gap. The plugs should be the NGK's EXACTLY as specified in the manual - no substitutions. The gap should be set to the decal in the engine compartment. Don't assume the plugs come out of the box with the right gap.
It could also be that if boost is being limited, the engine could be knocking, and the APC is cutting back boost. If the spark plugs don't turn out to be the problem, try running a tank or two of higher octane fuel.
