Just put in a fresh b16 obdo from hmo. Runs fine. But wen I start it up, it will bog right wen I go . Once its warmed up and idle reaches 1200 rpm. Its good to go. Seems like its running to rich or too lean. That's my guess. Has a chipped ecu. But idk wat the previous owner tuned it with or how he tuned it. No cels. Only mods are chipped ecu, intake. Header. Exhaust.

Anyone got any clues wats going on? Also blows some smoke after 5k but its not oil or coolant being burnt. Maybe gas?
