Hey all. I want to share my experiance here. I have spent the past few YEARS tuning with what turned out to be a bad MAF. Now it runs great with a stock APYP bin. It needs a tiny bit of tweeking but good. In the early days I did a hot trick of descreening abd gutting my MAF. That seems to be my mistake. Yeah I would get a code now and then but it would go away. All the changes I made were just chasing rabbits. Moral is make sure the fundamentals are sound first. It may save you a lot of trouble.
