When I was getting my car mapped a couple of weeks back, I asked the mapper (Bob Rawle) should I bother putting an I/C spray on my forester? He said I'd be far better off going for water injection instead! But not untill I uprate my pistons!
So answer is yes! any water injection would decrease detination and allow the mapper to advance the ignition and hence more power!
I think!!!!! bare in mind I'm a carpenter not a mechanic!
