Shift at 35mph off launch stay in fourth gear at the end since four gear tunes are generally faster. Also throw rally trans and rally susp on if you havent it makes a huge difference. Lower your tire pressure to 15.0 on both since it is a drag race it isn't a huge race at all.
Id like to know your entire tune thru the car, Ive been killing myself to get 273, all i have found is crappy youtube tunes thats all fluff and no go or show
