My sdl is supposed to hit anywhere from 121 to 130 mph. I don't know why the range. Perhaps it's trap oxid vs no trap-o? I have had it to 120 with more to go...

Got a new speedometer this week, hit 100mph quickly then climbed for a while to 110 going up a hill and into traffic 4100-4200 rpm and nailed to the floor, of course had to slow down before the traffic. I think it may max out at 115 possibly 120 with lots more road...Max power is suppossed to be at 4600 rpm in the owner's manual. I don't like to run the car that hard and pissed me off when all that traffic "appeared."
