You'll get used to it very quickly. My first standard was a brand new 2013 subaru wrx and I was scared and anxious to drive it at first but I got the hang of it after 2-3 days. You should be confident with rowing gears and learning the clutch in no time.
Thanks! I just wanted to make sure it was possible to run that tune with stock modifications.
How is it going for you now? is it running smoothly and no problems?
