I have been fighting a boost leak problem for a while now.
I charged the intake system with a compressor at 20PSI and found a leak at the Greddy FMIC elbow. I went to Mazda and ordered a new TB to TB elbow o-ring thinking that was the problem.

I installed the new o-ring and charged the system again and still can feel air with my finger coming out of the where the TB meets the TB elbow at the bottom corner on the firewall side.

What the heck anyone had a leak in this area?

I pulled th UIM and now only have the FPR and injector bleed vacuum hoses under there now so it's not leaking under there. I got a new o-ring and rtv glued the TB elbow on. I pressurized the system from intake pipe to right before the TB elbow and it is air tight. The only leak I have is near the tb to tb elbow connection i described above.

Anyone have any ideas about why it could be leaking in this area someone suggested it was the secondary injector bleed and that it might be normal?
