I'm wondering about how long it would take to tune a car for water injection given the following conditions.

First the car is turbocharged and running an aftermarket software. I would have the company that produced the software do some additional tweaking with my current software, to take advantage of the water injection.

I have the 2D system with an accumulator. I have figured out the correct nozzle size for my injector flow rates for a 10% ratio water to fuel, and have set the turn on level of the W/I at the point where the stock boost level peaked. I wouldn't have them make any adjustments to these things. (Should they?)

They have been tuning this model car for a number of years, have a dyno and the other equipment necessary to revise the engine code. They have also tuned this model and others to run on race gas. They haven't done a water injection project though.

Anybody have any experience on about how much time it would take to get a water injection tune? Any educated guesses?
