Peter,

My best 0-60 was 5.1, per g-tech (and I did several back-to-back runs that were comparable), and 1/4 mile was 13.38 (Gtech).

At the track, the best I've managed is 13.8 @ 102.1 MPH

I'm inclined to think the Gtech is pretty accurate, given how close back-to-back run times have been, for me anyway
