Moin people. I plan a little tuning on my SL this year. This also includes the VMAX at the Sl 500. I have model year 2007, so with 5.5l and 387/8 hp Currently the car is locked off at 255km/h. But… How much does that drive if it is “open”? Tires at the front 265 and at the rear 285. Had in the summer when it is well warm at 255km/h about 3500 turns. There is still something going on normal or? Who knows more about it? Bzw who is a serious company that makes the V/Max with Tüv? MfG Andre
