after it has been run in a quick run up to see andy f what power gains should i expect and is there anything else i would need like uprated injectors and what not let me know cant wait

 

you will need a fuel regulator
power is turbo dependent
3" through exhaust
maybe bigger injectors ...depends what you have at the mom
uprated gearbox/ clutch
