Should the nitrous nozzle be before the iat sensor? Or does it matter at all? Truck has a single turbo

Needs to be after. There is a case to be made that when using methanol injection, it makes sense to use the wet bulb temperature effect to artificially decrease the measured IAT so that the IAT spark advance table adds additional timing due to the additional knock resistance from the methanol. The same is not true for nitrous. Adding spark advance artificially is the opposite of what you want to do with increased oxidant.

Thank you. I was think of it backwards. Thought it was adding more fuel when it was colder out and not the timing part.
