Relocating the MAF into the charge pipe.

I should make my own mod thread for all of my mods but I don't plan on doing much. I just want to do some few simple mods to aid in tune accuracy and consistency. The best mpg's is the main goal because I have another vehicle that fulfills my power needs.

The reason for this mod is to allow the maf to see the actual airlow the engine will be ingesting. The problem with having the maf at the inlet of the compressor as opposed to in the cold side charge pipe is there could be a huge airflow difference between what the maf is reading from what's actually in the charge pipe due to pressure drop and IAT differences. If I move the maf into the charge pipe, the maf will see the true intake air temps and a more consistent airflow reading improving maf tunability throughout the operating range. Iat's can differ 30*+from the inlet tube to the charge pipe so the ignition timing tables will control timing much more acurrately and consistently as well.

I would really like to see the results of this mod. Seems to me it should work perfectly. Wonder if something like this would work on a stock gen1. Have heard of other vehicles having drastic changes to relocating the MAF for more accurate reading. Lets see some results!
