Default Iats What should they be at WOT

My 07 Trailblazer ss has a magnuson MP112H supercharger on it.

It is a stock motor ,LS2 .

My buddy has the same setup I have with the supercharger , efans, running about 6-7 lbs of boost., headers etc.

He installed one of your meth kits and he is mixing his own mixture , 50% Methanol and 50% distilled water and putting it in his wiper fluid resevoir.

He has a dashawk which he monitors his iats , ect, aat's, etc. The mechanic told him that he should be seeing his iat's dropping drastically if he is getting enough meth into the CAI. His nozzle is about 3-4 inches away fro0m his throttlebody .

I am wanting to add this setup to my TBSS also but want to make sure it is working properly on his first.

It is about 70 degrees here at this time of year. If his iats are at 150 degrees after sitting idling in the staging lanes and he pulls up to the tree at the starting line and nails it to go down the 1.4 mile track , should he be seeing his iat's dropping once the meth is injecting ? If it should be dropping , how much should he be seeing , I have been told by a few other guy's that he should be seeing it drop down to about 80 to 90 degrees after a couple of seconds at WOT if he has installed the correct nozzle .

Would love to hear your suggestions

Thanks in advance !
