It will cause problems if sprayed on the MAF sensor.

Mine is mounted to the front of the plenum.

EDIT: Then again, I have no MAF.

run it after the MAF, but before an Air Temp sensor. that way you can take advantage of the cooler air. Then if the system failed or ran out of meth for any reason it would notice the rise in air temp and it could pull timing

I used a 90mm TNT power ring and plumbed two nozzles into it.

Does everyone have their IAT sensor between the nozzle and the intake? How close can I have them together?
