Message	Taking a guess at the lack of power and ability to maintain it, my first guess would be a boost leak, which would give him a rich mixture. If you determine there are no boost leaks, I'd drop the downpipes and make sure he doesn't have a wastegate open. You shouldn't be able to move the disk that covers the wastegate bore by hand, if you can it's already open. Run some shop air, with a pressure gauge tee'd into it and determine that the gates are not opening prematurely. As noted, native boost on sport 500s is 12 psi, and that's when the wastegate arm should first start moving (ie. wastegates begin to open). Good luck, Mark
