i ran a 14.0 without using the gears on my auto on 205 rubber on 10-12psi.
its more than likley your start offs that will get you. my first run EVER i ran 2secs slower than i am now. i ran a 16.4, my second run i ran a 15.6 and the last time i went i ran a 14.0.
its always how it is when starting out, just keep going a few times and get opinions from people that have seen you run. its usually the starts that cause slow times.
