when i first got my gli with 30000 miles, it ran pretty strong, you could feel the turbo kick in and everything.. now, just a week later, it seems like the turbo isnt kicking in as strong.. is this common? what do you guys think is wrong?

i have a 2002 1.8t, same thing as the gli except mine is 5 speed and is a bit quicker. But my turbo still seems strong, and the even pushes me int my seat. I say get it checked out

oh does a cel come on?

it still puts me in my seat as well, just not as much as it did when i first got it.. and another question.. whats included in the 50000 mile bumber to bumber warranty? are tires, air filters? TURBOS? ha

The warrenty that you have is Powertrain warrenty that covers the turbo

check for boost leaks ... if you dont have any get REVO chip and that will fix it for sure
