light mods will be fine, the best bang for your buck is get more high end with less focus on low end that will kill the clutch, your clutch should be able to handle some light mods, up your fuel with a 2nd stage nozzles, down pipe up the boost a few psi maybe and see how you like it, then get a tune.
my clutch stated to slip once i put on my gt2052 and a set of pp.764's. so id say just go with the next size up on your nozzles than stock with a tune. A better upgrade is all around is a bit into suspension to get a bit stiffer for corners with out going wild and sacrificing on comport. The #1 thing you should do is get a EGT temp probe and gauge and an oil PSI gauge, i recommend Auber digital set, well worth the insurance if you go big on fuel as you want to make sure you dont exceed EGT's. If you spend the money on a turbo, its well worth it for the insurance to make sure it gets enough oil and does not overheat. im glad i did and they can be wired up as they have relay's in them for things like water meth injection or other things.
as for keeping it simple, a 1 stage up on nozzles and a tune would probably be best and you would not need any gauges for that!
once you get more power, you always want more
one suggestion i have for you is to find a local autocross, its more fun than you could ever imagine and you dont need a fast car for it, tires help
