the standard cams will be fine, if you want a rolling road tune i could organise that at Power Engineering Tuning, drop me a pm if your interested.

as for injectors & turbo, it might be best to get it set up as it is for now, enjoy the power for a while then look at upping the power some more when you get used to it!!
when you decide to upgrade you could go for a T38 turbo or a GT series one, for injectors you could use greys of siemens, i would opt for the siemens.
