Yep, sounds like a problem.

What else can you tell me?

What mods do you have, what were you doing when it b0rked, how many miles, blah blah blah.

You really didn't include much info in the first part that would help anyone try to diagnose your problem.

Yeah, sounds like limp mode. If you had a boost gauge you'd see that the car will only give you about 5 psi for a brief second and then cut to 0.

Get your car scanned for codes. If you can't, unplug your battery for a while (i like 10-20 minutes) to reset your ECU. If you drive and your car feels good again then you were in limp and now you're out. It is always better to scan the car and then fix the problem, though.

It can also be a bad MAF. You may want to unplug the MAF and go for a drive. If you get your power back then replace the MAF and you'll be fine.

Bad coilpacks can be a problem also. Is there a stong sulphur/rotten egg smell coming from the exhaust? Tumbling idle?

As Nor said, more info, like recently chipped, pushing the turbo when limp was hit, etc.

This was happening to me too! Took it to the dealer and it was the wastegate.They replaced it and he runs like a tiger again!

Check the coil packs and spark plugs first then check for a vaccum leak. Also what light(s) come on and do you have the error codes ?

This sucks big time cuz I just ran into this problem, It started a week ago but i just gotten worse, I did an oil change, fuel filter change, air filter clean, and still having the problem, I get a check engine light but I have a problem reading OBD port, I've been trying to find the spoiler control module, which marcus Yelokt found it was the problem when he took he's car into the dealer, I've been searching all online stores but no luck, so Im gonna try the dealer on monday, so now im faced with lots of issues right now, and since I dont have a code I wont know exactly what the problem is

Could be a vacuum leak, bad N75 valve (wastegate actuator), bad coilpacks, etc.. etc.. or, as in my case, any combination of the above.
