well saturday me and one of my friends went out cruizin ended up on a long straight so we decided a 20mph roll. every other time i pull very easily but yesterday i just couldnt get him i know for a fact his car is stock and all i have is a short shifter my gf was in the car with me but i didnt think that would make a diff since she only weighs like 115lbs im just very surprised it seems like my car is slower then when i first got it. anyone have any theories ???
