I've been reading about how guys are running in the 7's for 0-60 times on stock 1.8t's. I went and did a 0-60 and ran a 10. Now there is no way in hell this car is that slow. I would assume the o2 sensor needs changing as i am over 100k but could it really hurt it that much? any other problems that can cause lack of power?

 

do you have a boost gauge... if you do whats your boost at.... if you dont you could try doing a boost leak check that would cut your power down.

 

yeah check also for vacuum hose leaks and vacuum leaks.. boost leak.. get better spark plugs, change air filter.. a lot of things can contribute to slowness
