no boost

[davidgtrr34]

I have a 2004 gti, auq engine code. my turbo wont boost, car is running sound, no noises, not using oil, no smoke or anything.
When stopped if I rev it I can hear the turbo spool but it wont spool under load.
Has anyone ever seen this before

[james2]

is it mapped if not, mine was lame before it was mapped 

[james2]

Also scan it for any faults. 

[davidgtrr34]

Its not mapped but it is running around 210bhp.
ive scanned it and no fault codes

210bhp from a non mapped auq

6 bar fuel pressure and 1.2 bar boost

It must be mapped. The auq was 180 standard anything higher I'. Sorry it's mapped.

To answer your question I'd take a guess that you have a boost leak.

its not mapped. Ive done all the work myself
mods are fmic, ebc, adjustable fuel pressure regulator, walbro 255 fuel pump and diode mod

Then you have made adjustments and your car would naturally need a map now that's your issue.

take the diode mod off, it might have chucked the car into limp mode. euther that or the actuator has gone soft
