A dyno tune will get you closest when it comes to peak numbers... but it isn't always best for ET.
Most serious drag racers use the drag strip as their dyno. They tune for best ET while at the dragstrip. Also most serious drag racers don't waste time and money on electronic fuel injection when you can go just as quick without it. A few guys will still strap their drag cars down on the rollers though.
