HI I HAVE A 01 BETT. AND WHEN I GIVE IT FULL GAS THE CAR PULLS AND LETS GO. MY BOOST GAUGE IS AT ONE BAR THE .5 BAR. ANY HELP WILL DO ...THANKS

 

its all stock . she has just over 100,000miles. i was thinking maybe a little tune up. plugs, fuel filter, kan airfilter

 

also check for a leak in a connection somewhere, I had a the same issue and it was just a loose boost hose. a free 5 minute fix.

 

also there is a metal intercooler pipe right off the top of your turbo it goes tword the passenger side and then down, and it connects to a rubber pipe with a very strange clip style thing. check that because thats where my leak was. stupid *** throttle body not having a cable
