You have the choice of 8 maps, all different and great. I'm also amazed by Terry's support, every time you have a problem, email him and he will get back to you within 2hrs. Never seem a customer support like that, just amazing.
For the exhaust sound, I unplugged the wire going to the left exhaust flap so it's open all the time, it will give you a much better sound and cost $0.
This is exactly what I run and it works perfectly. The boost gauge in dash is something you will really miss with the cobb, and the ability to fill up with e85 for a power boost on demand is amazing. As far as install/problems, don't worry. Its really easy and I haven't had any issues.
