Hey Daniel, Mate as above a simple ECU reset should help you. Take a look under your steering column for 4 connectors in total, 2 green (plug in together) and 2 black (plug and clip in together). They are quite small. With the car off and at operating temp. plug them in - turn car on and prime the fuel pump. At this point you should hear different relays and sensors going nuts and all being tested - radiator fans, etc.. If you do, they are plugged in correctly - start the car up. Take the car for a drive - it may be sluggish at this point and don't give it too much stick, just keep it going at a steady pace (40km/h or above is good) until you start seeing the 'check engine light' flashing. Read that link for more information on how to determine if it's giving you a code or not. Once that's done simply pull over, turn off car and unplug the connectors, start up and drive. Give it 5 mins of driving and it should be back to normal. Hope this summary of the procedure helps (I have to do it every other day on my car at the moment!). Dylan

dylan mate i forking love u . u have just saved me over 200 bucks thanks to everone for ther help

So I assume you have 12psi again ? did you check for error codes before resetting it ? May have shown a cause (ie a sensor error causing it to go into a 'limp' mode ?)

had no error codes but computer keeps going back to 6 psi so something keeps tripping it so yer still have to pay to have it checked

Hey Daniel, that is odd. Do you have the stock B.O.V. on your car at the moment or an aftermarket one?

Checked for vacuum leaks?

If you have the factory blow off valve, the one that recirculates it might be leaking. I removed mine and saw an increase in boost straight away.

When you see your boost level dropping is the car missing or anything? Does it feel like it is hesitating ?

other than the loss of boost the car is normal the only thing i have noticed is that the car is back firing a bit i have a turbosmart bov that is only on the press side vac side is blocked off
