Way to many people follow every bit of advice that others give them and end up spending a heap of money of things that were not needed 2 Link to comment Share on other sites More sharing options...
discostig Manual mode ________________________ All day, erryday Donating Members 13,798 Member For: 17y 20d Gender: Male Location: Probably above atmospheric pressure Posted 05/09/15 12:19 AM Share Posted 05/09/15 12:19 AM Agree with Mick. About the only thing to check visually is that the boost control solenoid hose that runs to the turbo is not off. I left mine off accidentally one day after doing the cleaning/lubing of the solenoid and could tell straight away what was wrong when it boosted up way too fast. The wastegate never opens to bleed boost. Link to comment Share on other sites More sharing options...

boost69 Donating Members 737 Member For: 19y 6m 25d Posted 07/09/15 02:47 AM Share Posted 07/09/15 02:47 AM I was told by a reputable tuner that you really couldn't do much damage to the car because it would it go into limp mode (car was stock standard)...but to be honest I didn't go around planting it, when it was in this condition...I did get the tuner to change the actuator, and I was told turbo came off to change the actuator...
