Auto Tech says "Never have nozzle before maf... Have a friend who says my car isn't running as good as it should and I'm going to break something because my dry shot nozzle is before the MAF.
He says spraying into the maf is not a good thing because it doesn't read oxygen levels and it is screwing up the readings.
What do you experts make of this? Here's a pic of my engine bay w/ nozzle in lid.

No offense but your friend isn't too smart. The nozzle needs to be placed before the MAF so it can add fuel. You just need to make sure your nozzle placement is correct for a proper A/F ratio.
Btw, MAF's don't read oxygen levels.

I say you should print off this thread and hand it to him. He's obviously not clear about the differences between wet and dry, and is bulking them together.
Although.... since he's your mechanic, you should have him "fix" it and get a new motor out of it, just be sure to get things in writing!

DO NOT LISTEN TO MR. TOOL. The guy does not know what he is talking about. Invite Mr. Tool to came on this forum and post his technical wizardery, lol.
Tell him to check these threads out.

He's a moron.
First, the narrow-band O2 sensors are completely inaccurate at the afr you should be running on spray. For cruising when you're around 14.7:1 afr, they work great. For 12:1 or richer like you should be around on spray, they're completely wrong.
Second, the MAF does play a role in adding fuel. The nitrous spray through it, and due to it's rapid decompression from 950psi, it changes state from a liquid to solid and drops in temperature. As your 'auto tech' should know, the cooler the charge, the denser it is...The denser it is, the more fuel needed to maintain the proper afrs. So you're fooling the computer in essence into making it believe the air temperature really is something rediculous.(well below freezing)...And then the computer compensates and adds fuel.
I know exactly the type of person this is, because I've dealt with them before. They fool you into thinking they're the ******* God of performance, when in reality they aren't ****. They'll run their mouth and be completely *** backwards, and talk someone like you into changing something and making an expensive mistake.

Tell your friend to fight me. Haha, kidding. nah, your friend shouldn't be giving advice since he is way wrong. Spray a dry shot after the MAF, lean out your motor, and sue him. Make sure he signs a piece of legal documentation saying he says it will work perfectly fine, he accepts all responsability and he will replace the motor after it breaks due to his retardation.
Make sure he signs it before he installs it after you MAF.
