All depends on budget really and what you want the mods to achieve for you
You will not turn the car into a super performer, even spending 1,000's on superchargers etc doesn't raise it to biblical levels...
Some good plans would maybe include -
Upgraded brake pads & rotors
CAI for even more lovely noise
Plenum spacer, exhaust & uprev for yet more noise and a little more usable & smooth power...
That should set you back around £2k maybe more depending on what you go for but you will totally transform the driving experience
You are right about chipping, it is not useless on its own but with the right mods it is much better, best to decide on what you want and get it all done prior to remap
