Im a pain in the backside, i´m always coming up with new stuff, but ive just bought the car and im tring to fix the little stuff.
1- when i get my car around 2k 3k revs it has a vibration sound, kind of two metalic parts touching each other, it is not the exhaust cos i´ve changed it today, any ideas?
2- when i push a bit more the accelarator , when the turbo is in full power it cuts like its stops getting air, but if I accelarate slowly it goes all the way to the red line, the air hoses look ok.
anyone had any of these problems?

Thanks to all.

1. No idea
2. Sounds like the overboost circuit is cutting in. Could be a problem with the APC or the wastegate stuck closed. I've also experienced a similar effect when the plugs needed changing. You could try that first, it won't do any harm and probably not a bad idea anyway.
