Yep because I've seen the torque figure go up to 317 not the 260 that was on the rollers, the only way of seeing if there's a difference is another run in the dry with warm tyres, the falcons don't like I've and snow I think the rubber goes über hard as coming home it was like skating on a wiff of throttle at 50mph were as I was being overtaken by fwd normal cars,
Time to change wheels and fit some winter wet tyres, I just don't like to drive it on these tyres in the cold, I can put up my summer dyno chart and compare them both?
