I know that humidity, sea level, temperature, tire press., and coolant temp play a huge role in drag strip performance! I didnt manual shift (just put it in "d" and drove), or play with the tire pressure! I did have a lot of fun though! looking forward to going again soon..maybe end of sept. when the weather is cooler! I did notice the strip was slipperier than the street as i'm not running sticky tires, so easing out of the hole is defineately the way to go!
