Good question.
Simple answer: no you will not mess anything up.

Better answer: you can get a tune now and enjoy 5 more hp for $400+. Then when you get a supercharger you tune it again with maybe another brand of tuner software. Or which ever comes/recommends by the supercharger kit. So, buy it once then buy it again.

What it comes down to it is what your wallet says. If it was me wait till you get a good supercharger kit.

My only tip for newbie is to not start "modifying" anything yet. Enjoy your car as is for now. Leave the engine alone for a while. Start with suspension, brakes and tires. Start with a few track days to get to know your car then at that point you can figure out if you want to drop lots of money into a slow car to go fast, or so you want to drive a slow car to go faster. (Aka become a better driver).
