I have had a standard uk my99 for a year and a half.

I finally decided to change the standard back box for a prodrive W R Sport one.

I can't believe the diffirence.

The acceleration feels MUCH looser, i don't think it is as quick when the turbo picks up (ie around 2500 - 3000 revs), however when it gets higher up the rev range it is at least as quick as the standard box maybe quicker.

Could any body help explaining what has happened to my car and whether the power and torque has actually increased, as i'm pretty clueless.

Thanks
