Just got home from a 550km trip to a family wedding in the south west. I had it in dynamic mode and sport on the tct for most of the trip. On a few occasions when in 3rd gear behind a road train I gave it a boot full and it started to want to track all over the lane. Not real good next to one of those. It feels like its loosing traction. The only modifications are ragazzon system(Turbo back) and a tuning box. I am thinking the Pirelli tyres may not be upto the job, but it scared the crap out of my wife. Any ideas?
