I will leave it to those with diesels to explain the injection point more clearly, but it is my understanding that if you can inject the hho before the turbo there will be little to no vacuum at all. The manufacturer states to inject after the maf sensor for gasoline vehicles and may be telling you the truth according to their own experiences. But with this 773 kit you will need a better bubbler than what came with your purchase. Do a search for 'waterless bubbler', one of these can be built fairly cheap and should work to clean the electrolyte out of your hho gas. I believe that the owner of the waterless bubbler idea also said that you could run this bubbler on the vacuum side of a system, but I would send them a message or reply to the thread to make sure first.
I hope this helps, please let us know if you have more questions.
