Glad that I didn't go for larger camshaft, picked the VCM532 instead. There are plenty of rumbles at idle, the 3" exhaust tips filled up the space and look awesome. The workshop did a reasonable job, the ute drives very smooth and response is instant, engine bay is very tidy, the "sound enhance" pipe is removed. There is a remote control for Varex Box to turn it on or off. The guy at the workshop says 307 kw is reasonable for the VCM532camshaft, more if larger cam was fitted. The dyno numbers vary from one workshop to another, really depends on which machine they use. The mid range acceleration is really noticeable, I were pushed back into the passenger seat when the guy took the ute for a test drive. Filled the ute up on the way home and will find out the fuel consumption in the coming days. A oil pump is also fitted to replace the stock oil pump, the guy at the shop says the stock oil pump isn't as good. As I were saying, it is cheaper in Melbourne/Sydney but better having it done locally so I can go back to them if anything should go wrong. Will try to post some photos in the coming days.
