cheers mate i'll prob turn the boost down then and see if its been chipped etc then take it for a tune up. Just a quick one mate i drove it back 177 miles without a hitch running very low boost, however when its hot is it normal for it to make a slight bubbling noise from the turbo hose to the thermostat pipe?? it dont over heat and the fan etc works just after half on the temp gauge??? i just dont no much about them
