panel free flow inlet filter, sports cat free flow, new 02 sensors new timing chain if not been done is past 40k ie every 60.000 miles is best practice with them especially when mapped for all the power, also oil cooler and updated thermostat housing, then a bigger inter cooler,, and the biggest bit it needs is time on a rolling road to set where you want the power and how far your wanting to push it, more power more heat more risk, and when do really get to use it all as front wheel drive cars are a battle with that an=mount of power going to front wheels and front wheels need to steer and stop the car as well
