Mods in Sig. I had just finished a round of maintenance and was driving around town when a blue 18 Camaro SS came up behind me after weaving around traffic. Dude was posturing, revving, etc. We lined up at a light and I figured I had a pretty good chance since he had a manual. I was able to flash the stock tq. converter a bit as the light hit green and got a good launch, and only slight spin on the 1-2 shift. I got a car length out of the gate on him that he never recovered from. I slowed down to try and talk to him but he got behind me all of a sudden and did a turn of shame of onto the nearest street he could find, he didn't look very happy in my rear view. I drove by the local Chevy dealership and saw him there a few minutes later hanging around. I'm pretty sure it would have been a different outcome if it had been an auto.
