Ive owned my 1999/2000 audi a3 quattro ajq 180 for 18 months now it has been chipped to 217bhp with proof,
since owning it i have replaced injectors and fuel pump fuel pressure regulator air flow meter because of bad hesitation and low fuel pressure. I have also fit a boost gauge and it hits 20psi and drops to 12/14 psi.
The problem i am having is that it has always been low on power the last time it was on the rolling road it only pulled 165bhp, compression test is good on all cylinders no boost leaks no fault codes.
Now when i drive down a long hill just letting the car ride with no throttle i get a big puff of blue smoke when i rev it this is the only time it seems to do it no blue smoke on start up or idle so i dont think valve stem seals could all these problems be down to a faulty turbo
Any help would be greatly appreciated
