Cylinder charge temp bias with meth injection

Cylinder charge temp bias with meth injection Was talking to a tuner buddy of mine at the track and he brought up that I need to adjust the cylinder charge temp bias towards ECT since with meth the IAT is not accurate anymore.
First of all, is this correct? After all, the inlet temps do drop when meth is sprayed, possibly not by the margin the IAT shows, but there is a temp drop.
Second, lets say I bias it fully towards ECT, what is this going to do to my existing tune? I am afraid to move it too much as I don't want it to lean me out or something. Right now it is very skewed towards IAT (.0xx out of 2, with 0 being full IAT and 2 being full bias towards ECT).
Any input here?
