I bought my 2013 SHO right under a month ago and finally got it to the track. I picked it up used with 27k on the clock. It has an Airaid cai only from my knowledge. I don't see anything else. I even looked at the map sensor and it is stock. My very first run I ran a 13.019 @106.34. That was in 64* weather. I ran 4 more times and in 90* heat I was able to run a 13.017 @ 105.83. I'm really impressed but is this normal?
