IF it is going to be SD then just weld a bung on the charge pipe before the TB and install it there.

Depending on if it is LS2 or LS3 you can look up the 5 wire pinout for either man and run the correct two to the sensor.

I like to use the LSA IAT2 sensor. You can take the break points and cure from an LSA tune for the IAT calibration.

Its LS2 - I was just trying to keep **** off the charge pipe to keep it clean of extra wires and ****.. and hide what i can.. I dont tune so any of that calibration stuff is on Dr phil

I put my iat on the bottom of the charge pipe just before the throttle body so it isn't seen from up top, it looks cleaner that way in my opinion

I was also running dual meth and had the nozzles on top of the charge pipe just after the bend where it comes out of the intercooler... I never had an issue with it

Put the meth further back from the TB and the IAT right before the TBG in the charge pipe. This is better then putting it in the manifold when you have the room on an SD setup

You can put them on the bend coming up from the IC. Don't go further then that.

Only problem is at the bend will hit the cover. Have to figure out something. So bend or closer to tb but not before the bend. Getting a new 3.5 pipe made have to see what I got after I cut it to fit

meth nozzles are on top, only the iat is on the bottom... this is the best pic I could find on my phone but you can see where the nozzles are... iat is as close to the throttle body as I could get it with the coupler installed
