STi lag problem

My friend just bought the new 04 STi has had it for about 4 weeks. He is sayin that it feels like he is driving with the E brake up (no its not up) anyone know the problem with this.
THANKS

Can you get a little more spacific. No Boost? Noises? Vibrations? Bad Gas?

yeah what kind of gas is he puting in it?

It feels as if there is a constant hesitation as if you were driving with the parking break on. He is putting Supreme 93 octane from Chevron

What is the center diff set at? If it's fully locked, it will have a bit more drag on the drivetrain, or in Auto mode there is a slight delay when it changes settings.

If he has a boost gauge check to se if it's building boost. one of his hoses may have come loose. Is it making any strange noises? It might just be bad gas. My buddy has a turbo civic and it runs like a bat out of hell. He went to the track one day and put the usual 104 in it and it ran like crap. come to find out some water made it's way into the gas. The same thing happened to me on my Hayabusa. No wierd noises just wouldn't pull.

Is this yours and your buddies first experience with a turbo car. Not trying to talk down to you or anything. just trying to find out where your coming from.

yes the Diff is set to auto. And yes this is our first experience with a turbo car thanks for the help

I forgot to say that he rans his car very hard even when he got it. So i was thinking maybe he messed up the piston walls

If it's new yake it to the dealer and let them figure it out. That's what warranties are good for.

Yeah but I wanted to know what was goin on before i took it in for future refrence thanks

Thanks for the help guys I will try these things out and get back to you all

i know!, your friend needs smack in the back of the head for not breaking in the car before beating on it, jackass....
