hello, i just bought my first car 2012 seat Leon in 1.2 tsi, (77kw, it was owned by leasing company so completely stock with good history)

and I was wondering if its worth it doing some stage 1/ stage 2 mods? (chip, air intake, downpipe or whatever) or to keep it stock as a reliable daily ? I really wanted more power but this car was greatly valued and I was swayed by the history and the yellow look. Still iam kinda not sire about it, even if iam happy I still wonder I could have more power. is it worth tuning the 1.2 engine? I already bought new rims and wheels with some looks customisation though.
