I dont understand what U mean. "A 40 shot making a 1.14 and 6 mile an hour difference?! You miss a couple shifts on the dry run or what? I just don't see it". Should I be faster than that? I have an auto, so I dont shift the car. I have added some wieght to the car like strut tower bars and sterio stuff, so If I ran the car now I would probabaly run like 15.4 or 5. Hope to hit 13s soon on the NOS.
