With the GM stage 3 do you spray nitrous before or after the MAF sensor?
In other words is there any plumbing differences between a dry system with Stage3 ECU vs. OEM ECU

Preferably connected to the intake manifold you never want things spraying on the maf itself. Im not as I havent put nitrous on my car but I hear that people have had issues with in taking the coating off the rotors.

With meth. Not Nitrous.

I personally have never had problems with meth running thru the s/c but i guess each person has thier own problems.

Some have some havent, but regardless nitrous has not been known to take the abratable coating off the rotors.

I thought the nitrous was supposed to run by the MAF so the nitrous map in the PCM can see what is going on? could be wrong though

Yes a dry nitrous setup sprays before the MAF, I was wondering if using the GM st3 ECU was the same nitrous set up.

the same nitrous setup as what? the gm s3 one is a dry setup.

The GMPP S3 has you installing the nozzle after the MAF. All fueling and timing tables are controlled by the PCM. Once the nitrous system is armed, the PCM is signaled and all timing and fuel tables are controlled by the PCM. The nitrous will not take the coating off of the M62 rotors.

The GM directions that came with the ECU said nothing about location, I dont want to spray a bunch of nitrous into the motor and not have enough fuel to keep it safe.
I had a wet system but i am going to convert it to a dry system since I now have the stage 3 ECU.
