I am looking into prices and options for a cam and tune for my VE series II GTS with an LS3.The car currently has 325kw,and I would like extend that to around 400kw without spending excessive dollars.Can you help me with my quest?

If you're specifically after a cam and tune to suit your VE GTS LS3, coupled with the fact that you're located in Diamond Creek, then we would recommend Electronic Automotive as shown in the link below (best to call them) http://www.electronicautomotive.com.au/ Another option to consider, which would yield similar gains to that of a mild cam at a more competitive (especially if you include labour costs with each upgrade) would be our higher ratio rockers as shown in the link below http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectID=2350330
