also might be worth mentioning that I am not experiencing any symptoms that the engine is lean. (loss of power, rough idle, smoke from exhaust etc)
At one point I did have a misfire but it was due to a spark plug.
Hi there. I have a 2006 Mustang GT that I've had for some time and decided it was ready for some modifications.
I've added a SR Performance Cold Air Intake and drove for months and no issues.
I decided to throw on some shorty headers, Flowtech, to be exact and have had nothing but issues...
