So I'm pretty new here but I just picked up an 07 with a myrtle west 330 kit on it. I picked it up last week from a dealer in NC. The only issue I've noticed so far is that when I'm running 75-80 on the interstate, I seem to be getting passed by everyone. I don't know where the Speedo sensor reads from though. I'm used to cars where it is the overall diameter of the tire that causes the issue. But the 330 is only 0.3 inches higher in diameter so that should be a very small difference to the Speedo. Am I missing something? Is this comon? Or maybe everyone is just flying on the interstate lately lol.
