I second this question.
Does the nozzle go before the iat sensor for my haltech?

probably either way will work w the appropriate tuning.

i chose to relocate my IAT sensor from the UIM so as to avoid any heat soak problems.

i decided i did not want my IAT sensor shocked by the alcohol. i did not want my air temp correction tables involved. i prefer to have the IAT input fairly constant and tune for AFR, Knock and EGT by using the base fuel and ignition tables.

i think it works well.

So where would a good place be to install IAT?
At this time, I think I want to just use water. My main goal is to be able to increase timing to gain more torque and quicker spool.
With that being said, it is like saying I am only going to redline once!

And is there a difference in tuning for drift only applications? Meaning, (I think) lower engine load because of less tracking, yet faster engine revving.
