The bhp results they produce is complete wank

But the 0-60 times + 1/4 mile times are pretty damn accurate

I did a few runs 0-60 @ FCS this year, and used the g-tech meter aswell to test it, and it was 0.01 different from the times that the organsiors recorded

And in a 1/4 mile at pod is was 0.02 different to my actual time, so a pretty good guide
