It all depends...were you racing a C6 LS2? or a C6 LS3? The average LS2 would trap around 113-115. Given your mods and seeing you are non-intercooled, I doubt that you trap over 112. Especially since you have 3.29 gears. Is it impossible? No- obviously not- you did beat him. Was the driver mod at play here? Yes, definitely. He probably started off in too high of a gear. That is in no way your fault and you made him pay. Good kill.
