Hi Just want to introduce myself as a new Camaro 2SS owner. Bought the car about a month ago as 2011 leftover and I felt that I stole the vehicle from them. I have never been a big fan of automatic, but with a bad left knee the manual was not reasonable. When I first got the car the dealer used 87 octane, since that tank I have used 93 and with the use of the iPhone been getting constant 0-60 from 4.6-4.8 seconds. I found that if you use the speedometer and not the digital you will be more accurate with the times because the numbers do not jump. Lots of upgrades to came. I will have a picture soon but there seems to be an upload problem, will try later. Thanks Ed.
