I ran mine for over a year no problems. Has anyone checked the codes? ^^^^ do you have codes or going of butt dyno. These cars run so rich from the factory that intakes alone wouldn't cause a lean issue unless you have leaks in the system after the MAF's. Try cleaning the filter, Over a year should be cleaned anyways and clean the MAF's.
I have a friend who was fully bolted , Headers ETC, and wasn't so lean he had problems. He drove it that way for over a year before getting a tune.
