Anyone have a Billet and ported Vf43
 

I'm thinking of porting and adding a billet wheel to my vf43.

Spoken to my mapper and he reckons there's upto 25bhp to be made by fitting one.
Not a bad increase for such a little expense.

Technically thinking a billet Vf43 should make round 400bhp and spool even better than it does already.

Does anyone have experience of one or have one fitted to there car.?
If so what power was it making?

I know replacing the turbo would probably be better, But a decent turbo injectors and mapping is looking to be around 2k and I have more important stuff to buy at the moment. In comparison a new turbo core, billet wheel, balancing and map tweak is £500.

Thanks.
