Ok fellas,time to dispell your fears of the dreaded "Reflash". The reflashing of the PCM in all BA falcon range(N/A,TURBO & V8)will not affect the boost control of the engine.Whenever a PCM is reflashed it is usually to do things like remap the fuel system or install diferent calibrations for auto trans operation. If your T is loosing or has significantly reduced engine performance there has to be another reason.I have heard of this problem before but have only seen 1 actually play up when test driving it. After driving the vehicle for approx 5 km make sure the car is in top gear(5th for manual and 4th for auto in sport shift mode)slow down to about 70kph then accelerate again. When the vehicle starts to pick up speed it may start to surge. If this happens then you have a PCM fault that will NOT log any DTC's.What this is is the "C" connector in the PCM has not been plugged in properly and has either fallen out or is sitting loosly in it's hole. If you look under the PCM the "C" connector is the one furthest from the firewall. Put your hand under it and gently push it up.If it is partially out it will move and you will hear a distinctive click as it locks in to place. By the way guys,your dealer should be able to monitor your boost variations a lot more acurately with thier WDS than your aftermarket guages do while you are driving the car with them. If they dont know how to do this then find a dealer that has tech's that do.This is also a common problem that they should be aware of so dont take any of thier crap.
