depends what your looking for dude? a hybird is still gona give you the response you want and good enough top end power, prob make say 200bhp! a td04 will make you more power and kicks in alot harder but is a wee bit laggy (not that bad) generally seeing full boost around 3.8-4k , but yea an actuator, fcd and rrfpr and get it set up on a rolling road to measure a/f ratio at 1bar would be fun. or you can go down road of management, personally i would do this
. all in all depends what you want from the car. and btw where abouts in co down you from lad?
