      I can only come up with 3 logical solutions. If you have any other suggestions, please do submit.

      1 - Tune the fuel tables to balance the unmetered air, which should be at a constant value in reference to RPM.

      2 - Place the MAF before the compressor and route the BOV back into the intake after the MAF but before the compressor

      3 - Use a Speed Density OS and route the vacuum line to just before the compressor to get filtered, uncompressed fresh air.

      Each one has its merits.

          I like option 1 but option 2 seems more professional. Being so, I'm probably going with option #2.

          You suggested using 70% Valvoline MaxLife Dexron III ATF and 30% Caterpillar 8T9572-30W Hydraulic Transmission Fluid.

          If I can not locate a source for Caterpillar 8T9572-30W Hydraulic Transmission Fluid, would this ATF work well? It seems it would be perfect for the application, just want to be sure cause the stuff is expensive, $10.25/qt.

          At 8 quarts, $82.00. Or possibly mix 50/50 Valvoline Maxlife and Amsoil Racing ATF.

          Would you recommend Amsoil Super Shift Racing Transmission Fluid? I never trust the advertiser, only experienced users.

          Amsoil

          Yeah, I would have to purchase a 2-Bar MAP and scale the PCM tables as required. But that can be done. Only thing is I heard Speed Density is not as good as using a MAF.

          I may look into that more before making a final decision regarding.

          EDIT: Just read this...
          Note: AMSOIL Synthetic Super Shift® Racing Transmission Fluid is not recommended as a replacement for Ford Mercon®, GM Dexron® or Chrysler ATF+ type fluids in passenger vehicle and truck transmissions as it may cause erratic shift patterns, chattering or noise. AMSOIL is not responsible for transmission performance inconsistent with those specifications listed and where transmissions have been modified from the original manufacturer’s design.
