Riv,

Check your Turbo hoses for any leaks. Some splits and breaks only open up under boost. Dumping intake boost from a bad hose can fool the ECU into thinking a lot of boosted intake air is coming in, but it's really escaping after being metered. The result can be a very rich mixture. Increasing you boost with the D-device may have caused an intake leak some where. I know your hoses are new but I'd check them and the intake connections carefully anyway.
