I am not turbo savy, but this generally sounds like a fuel-quality
problem. The computer may be retarding the spark because the knock
sensor is sensing knock or ping. Try a tank or two of high-quality
(name brand) premium fuel.
Otherwise, you are giving it more air but it isn't getting more fuel,
so suspect an air leak between the AMM and the throttle body or a
vacuum leak somewhere.
