Ok, on my way from TN to ATL I saw an MX-3 on 75S. We both Took 285 (going towards Augusta). When the two lanes merged from 75s onto 285 this MX-3 took off. I dropped down to third and passed him in forth. I figured it had to be some sleeper. I tried to slow down again for another round after activating the boost controller but he didn't bite. Good run!
