My car started to sound like a busted old mustang/helicopter. A code finally popped up and we figured out that the fuel injector in cylinder 5 stopped working. Had it replaced, it's been 2 days now, and I haven't had any problems with it. I'm still getting 5psi boost vs 8 but I'm pretty sure it's from the same part that leaked before. I will definitely update again if this was the problem.

I'm going to be SO MAD AT STILLEN if this was the problem. First, they sent me the wrong map when I got the car and told me I'd have to wait 2 weeks before they could send me another one. Then, the small plastic part that was crushed and was causing my air leak "wasn't covered" by the warranty and they wanted me to pay $15 shipping for like a $5 part. AND NOW a faulty fuel injector???? I spent thousands trouble shooting and Stillen didn't help me through any of it. When people on the forum said stillen aint what they used to be I should have listened. Done venting - stay tuned for more updates
