Rough Idle & AFR bouncing.

Hey guys, got a 2007 Mazdaspeed 3 with rough idle along with afrs bouncing everywhere and running rich. Main mods are 3.5inch intake, corksport catless exhaust system, bnr s3, autotech internals, vtcs deleted and front mount. I have already done a boost leak test and came back with no leaks so I am confused on what the issue could be, my tuner at cyborg said boost or exhaust leak but I have checked and it’s all fine? Any help is appreciated 🙏
