TDV8 Intake - Chemical Cleaning

I am planning to carry out cleaning of the intake system of my 2010 TDV8 using Liqui Moly DIESEL ENGINE INTAKE DECARB. This requires spraying the product into the intake just after the throttle butterfly valves while the engine is operating at 2000 rpm.

http://www.liqui-moly.com.au/diesel-engine-intake-decarb-2730/

The standard way is to remove the hoses just before the throttle valves and spray the product in.

My question is will the engine run with the hoses running from the intercooler removed as air intake will not be through the airfilter and and subsequently no airflow measurement. You have to run the engine at 2000rpm during the spraying process which seems quite a high speed to run the engine at with no load - and for quite a few minutes. I was thinking of removing the air temperature measurement probes located just after the throttle butterfly valves and inserting the spray pipe through the resultant opennings as an alternative.
I realise with the intake system not fully installed a lot of error codes will be thrown up, but I can reset those afterwards.

Any thoughts.

The TDV6 will happily run with the hose disconnected. (I left electrical connectors connected)

There was a story on here where by someone destroyed the engine buy doing this sort of thing.
The liquid pooled in the intake and then was drawn into the engine together.
Liquids in the compression chamber destroy engines!

Yes there are a lot of carbon deposits in the inlet on these. But I would rather they be there doing no harm than blown through the turbo and CAT

My thought exactly.

Don't see the need to do this if you're using half reasonable fuel. If you must chuck something through, use a fuel additive. 2008 TDV8 - it's a labour of love
