everytime i run my performance tune i end up getting dtc code p0175 (b2) system too rich... all my tunes are 93 but i only get that code when running the performance tune. i can drive the race tune everywhere and not have a problem. just the performace tune is the one that throws that code. i dont even run the street tune.. any ideas/knowledge on this? i do have a bbk cai.. and i put that info in when i requested the new tunes... it a 2010 v6 btw.
