Won't spraying through the MAF screw with your tune?

I'd put it after the MAF and not before..

 

If it's a dry kit, the nozzle needs to be before the MAF. That way the MAF registers the nitrous and the computer adds more fuel. However, since nitrous is very cold, if pointed directly at the MAF, the wire leads will freeze and be unable to read anything, therefore leaning out the car. A lean car on nitrous = a big pile of broken internals.

 

I run a plate system now so it doenst matter, but I used to run the 5177 kit. Suppose its much better since it runs in through the lid? I always wondered about freezing up the MAF
