You know I read the forums for weeks before I did the install and I about decided not to touch my car after hearing all the horror stories.
I had purchased all my stuff and had it sitting in my bedroom. I just couldn't stand looking at it all sitting in the corner so I installed it all. Yes, all of it at once. (shocked)
I figured that something would go wrong....nothing did. No boost cut, no CEL, no fuel cut, Zip Nada! I have about 500 miles on the clock and am not worried about a thing.(omg) Oh yeah! One thing....I got my first ticket in 20 years last week!
