^^Probably^^. Snag there is you have to be at a tuners garage to have the bias out of it unless you have a tuner come to a r/r to swap a file.
To be honest though a car showing slightly better numbers on the dyno doesn't automatically mean it will have good performance numbers on the road. And how do you declare a winner? Highest peak numbers or the overall graph curves/area under the curves? Or a combination? There is more to performance than a rolling road plot. And tiny %'s of difference will be negligable anyway. And on the road, a **** driver won't take advantage of 2 extra bhp or 5 extra ft-lb's
