I never said that I am going to tune my whole car with the MAF. I'm just saying that I believe I have a bad MAF. It wasn't calibrated right in the first place and so I had to buy an optimizer to fix it? I'll just have them recalibrate this one or I'll buy a new one and send this one back. I'm gonna look around as far as custom chips. I'll probably have my computer flashed. We'll see after I get the little things figured out.
