i agree with this. if you were to go e85 or get a bigger turbo, that is when you will be genuinely annoyed with your current fuel ceiling. but until then, and especially if you are not having a custom tune on a dyno, the limits of your current fueling wont aggravate you.
you could just wait to upgrade fuel at the same time you have a custom tune done for other big power upgrades
