While I was entering the interstate, I noticed a Lightning behind me already on the interstate moving at normal speeds. I merged at about 90mph and held it there for the L to catch up. He must have had some mods because there was some kind of aftermarket ram air scoop. I was in the far left lane and moved over to let him pass; well I wanted to see what he would do. So he gets about two truck lengths in front of me then hits the gas. I could tell because of all the smoke that cam from the side pipes. I down shifted into 4th and took off. I hit 5th and almost red lined it. By the time I got into 6th I was right beside him. That’s when he backed off. I looked at the spedo and I was over 140mph. I was catching up to him but I guess the L could not take anymore. What do you think?
