Boost problem!

[05GTLIBERTY]

Hey guys had a slight problem with the Lib today, it overboosted by about 5-8psi. So I pulled over and checked and found the hose that runs from the wastegate to the module at the front near alternator had come off, so put it back together and it's running like a pig and only on 14psi. Is there anything I can do besides checking all lines for correct fitment and cracks? Is it possible for the ecu to lose a tune?
Cheers,
Lloydo

Not lose a tune but the overboost has probably put the ECU into limp mode. Try resetting the ECU after checking that all the piping is serviceable and correctly connected

so just fully disconnect battery or just the earth or power?

How built/tuned the car?

It was tuned at rigoli's in Sydney, and put together by a mechanic in newcastle

I think Senator means how tuned is the car and how modified are the engine components etc, ie. it's running 20 pound of boost, huge front mount and tuned to within an inch of it's life - or - it's nearly stock, cat back and a mild safe tune…

That would help paint a better picture.

Bingo…thanks Ben

sorry Lloyd I remember you posted before the car has some avo parts and wasn't exactly stock

Yeah has bigger turbo, fmic, full 3" zorst, silicone intake, pod, bigger fuel pump and a tune. Has ended up being the wastegate actuator wornout/sticking/faulty. Getting new one sent up from avo under warranty.
