If you spray before the IAT you could tune it to pull timing if your meth stopped flowing and IATs spiked.

Always spray before. That way in the event the tank runs dry or the pump fails, the IAT spark correction will save your motor when the IATs rise.

I was just about to post this question! Not to hijack but how far away should the nozzle be. Wont that soak the IAT with the nozzle to close and give you false reading

theirs no way itll "soak" the sensor since the air coming in is hot as it is, and if you have a quality nozzle itll be injected as a very fine mist.

Yeah, it would be no fair to leave your poor IAT out. Always remember this:

IAT's like to smoke meth too!

i put mine about 6" before the IAT so it would have time to atomize better before hitting the sensor. Working great so far

I think the rule of thumb is 12" from the throttle body for proper atomization and it should be before the iat sensor. I know that's how I'd want it so that I can see how much my iat's drop when meth is spraying.
