My Magnaflow exhaust has been running a bit rich since my tune (blackened the 2 outer tips of my quad-tipped), but otherwise is perfect. Anyone else experienced something similar after a custom tune? No codes or anything, and I love the way she performs.
Better rich than lean, but if you're that concerned either get a wideband or ask your tuner what their target A/F ratios were. You have a performance car, every time you go WOT you will run rich. Also are you catless? You should see my Greddy EVO2 muffler on the inside XD
