Diesels are a completely different animal, and most use single turbos; although there are a few sequential turbo versions out there. The issue on diesels is that they are not putting much out in terms of psi, so there is less load/stress on the turbo. The EcoBoost engine is a true twin-turbo, not a sequential style.

The safest way to up the boost on these engines will be by using a programmer to reprogram the stock ECU. SCT makes a couple different devices that will allow you to load a custom tune onto the ECU from a tuner. A guy is already doing some pretty cool stuff with a SHO. So far he has upped the boost, changed the timing and fuel maps around a bit and also changed the shift points in the transmission.

I mis-spoke about the PSI. You are right, I know very little about diesels other than general function. The only diesel I own is in a Kubota compact tractor. Now, that being said, it doesn't change my opinion that people increasing the boost on the EB V6 is going to likely have much more dangerous results.
I do know that Ford had one hell of a time with the 6L PS blowing the heads/head bolts off of the block if hardly any mods were done. That being said, deisels are still a different animal, although with direct injection of the EB v6, they are slightly closer in comparison. They still make power through two different mechanisms.

Without seeing a compressor map of the turbos being used on the EB engine it's hard to say how much the boost can be turned up before it becomes a problem. All turbochargers have an efficiency range that they should stay in, when you move beyond the efficiency range of a turbo all you do is generate excess heat and shorten the life of the turbo. However any decent tuner would know where that point is and tune the engine to stay within that range. There will definitely be room for improvement in the power department on these engines even if the boost is kept at stock levels. Most turbocharged engines come from the factor with a very rich tune, just by leaning out the A/F ratio and changing up the timing you will be able to get a good bit more power out of these engines. Also tuning them to run on 93 octane only will unlock a lot of power as well. I personally can't wait to get my hands on a EB Powered F150!
