Hi mate would advise getting a fuel pump think they
are about £130 from amber performance.

Its a good idea to get one just incase you get it chipped
in the future.

If the car is not chipped at the mo the standard ecu wont
let you run more than about 10psi of boost.

As for power id say around 185bhp ish that is a ball park figure
mate.

Cheers matt
