Definitely not. Although it could allow the VAQ to do more with less intervention, even just putting the car in TC off / ESC sport setting gets huge performance gains as evidenced by many on track reviews and tests. VAQ equipped cars routinely shave several seconds off of lap times as compared to the base model. I'd also be wary of fully defeating the XDS as golfdave rightly points out, it operates as an integrated system and we don't actually know how it will respond if you take part of it away.So what I'm getting is XDS would have to be almost off to get any benefit of the FDL? correct?
