Cam needed?

[Jacque]

Hi,

Im currently running this setup: its near stock, apart from a tuningchip from SLS wich claims 144 bhp, but im pretty sure mine has not got that much i m guessing 130 ish but never been on a bench...

68mm pulley on a stock charger
bosh plugs(came with chip)
KN airfilter (inside stock housing)
4-2-1 exhaust manifold, sportcat & Group N muflers (roettele racing)

Im looking into some new mods, mainly on the inlet:
GT inlet & 51mm dewedged TB.

If i run a GT inlet & 51mm tb on a standard cam, will this give a powerincrease? Or will this be minimal with a standard cam? and will i really benefit from inlet & TB if the chip remains the same?

Ofcourse cam + chipping it on a bench will be much better, but i m not that high on cash at this moment, so im kinda curious on your thoughts!
