ok, i found some leaks in the injectors. they were blowing out boost and fuel (when under boost) go those fixed. but the maf is still a little irratic. not near as bad but still there. going to go sd hopefully in the near future.

now, back to meth. i see you don't want to spray it on the maf but you do want to spray it before the IAT sensor. so, what sensor do you buy and where do you put it? should i put it in the manifold or in the piping right before the TB?

 

The 2 bar sensor is off of a cobalt SS. P/N is 12580698. (courtesy of joe06ss)
You want to put it as close to the TB as possible and set your meth nozzle at least 6-8 inches away from the sensor.

 

the cobalt sensor is a direct replacement mao sensor. but i have to install a new IAT sensor. just wondering where a good place is to put the iat sensor.

 

I put my IAT sensor in the intake tube before the TB. It is about 5" or 6" from the TB. I have a silicone right angle connector on the TB and it is in the tube close to it about in line with the electrical connector on the TB and on the back side 90* from the top of the tube. My meth nozzle is in the top of the next intake tube about 6" further away. I basically copied Jerry2500 when he did his. He posted some pics if you do a search you might still find them. Seems to work well as far as I can tell.

 

thanks i'll do a search.
