i am working on a 2011 CTS-V, we put ported heads, cam, upper and lower pulley, ZR1 supercharger and CAI on it. now i have the P1101 code ( Intake Air Flow System Performance ) set. it comes allways when i drive it with WOT a few seconds. any idea to solve this? the car runs great before it goes allways into the low boost mode in a short time. its better to go back to the stock airbox?
