Question: Modification

Hi guys. So I’m not looking to do anything too crazy with my current 2016 VW Jetta TSI (1.4T). I just want to add a LITTLE more power, and make her look a little cooler.

Should I add another turbo? Increase the size of the turbo? Add a supercharger?

Are there any Texas recommendations for upholstery as the interior is a little dingy too?

I don’t know what I’m doing but I’d like to have a decent idea when I goto my mechanic or if I goto a performance car shop.

Any assistance would be greatly appreciated !
