I know i'm in QLD but prices would have to be similar. I had mine done at THE BROCK SHOP, Underwood, $197.73.
Rundown:
Dyno Run as received for base figure. Checked Spark Plugs. checked ignition leads for resistance. removed throttle body. deglazed carbon. reset IAC valve and decarbon. Download computer diagnostics and check for computer faults if any. check ignition base timing. visual check of computer connections in engine bay.
Results:
As tested: 105kw / 140hp @4800rpm
After Dyno: 111kw / 148hp @4800rpm
Handy extra 6kw for $200
P.S - VS stock standard not even cold air when dynoed.
