when i woke up today i towed my car to an auto repair place, he checked it out and didnt know whats wrong with it.. the codes are
480
481
2105
2106

so i changed the tune to 93torque and the engine light was still on.. then i decided to change it back to factory tune (still left the cold air intake in) and i noticed the car shifting weird.. and when i hit it hard, it sounds loud but it barely pulls (feels a lot slower than before the cai) i'm so confused and frustrated idk what to do..

by the way when i changed it back to the factory tune, the check engine light soon went away..

 

Depending on which CAI you have you probably can't run the car with the intake without the tune.....that's why the car is acting weird.....Only a handful of CAIs are designed to be rune without a retune. Put the stock intake on and run the stock tune and THEN see if the car acts right
