Just bought an '06 S80, 2.5T.

I have a 2000 V70XC with the same engine, though now it's uprated from 190 to 208 hp. I've read some threads about taking a turn on the nut at the wastegate to get more boost. Hey, it's a big car.

Facing the driver's side, do I tighten or loosen the nut?

TIA.

Neither.

The boost is controlled by the ECU, you can't reliably get any boost gain out of adjusting the wastegate, it'll still open at the same point, but if you turn it too far, it'll throw codes.

If you want more power do it right and buy a tune, you'll be way happier.

Well, that's kinda disappointing!

Thanks.
