The thing with adding nitrous to the intercooler is you not only get the nitrous but you're also getting a few extra lbs of boost as well, due to the much denser charge of air, and the effects of the nitrous on the motor and the wastegate not being completely up to the task.
I've played with nitrous kits on 1.8T motors and they usually get about 3lbs more boost on nitrous than they get off the nitrous, if your inject it into the motor, rather than just doing a spray bar setup to 'freeze' the intercooler if you will. Plus you always have to bank on there actually being nitrous in the tank. For *MY* application nitrous oxide injection is not the route i will be going for many reasons.
There are ins and outs to both setups, but i'm going with what *I* know, that being a water injection system, (pretty far off in the distance) such as the one from
www.aquamist.co.uk. I've had *GREAT* luck with that setup and it's charge cooling ability.
as for other AFC's that is a very good point. But for right now i have an AFC from a prior car that will be going in. until there is a setup like the LINK ecu or such out where it's a plug and play piggy back controller that the end user can actually tune with the right software/interface hardware
