Just days after it was introduced, Holley's all-new Sniper Stealth 4500 EFI is already powering drag racers to victory. Driving father Pat McCreery's dragster, former Jr. Dragster standout Mayce McCreery plowed through six rounds of eliminations for a runner-up finish the first time out with the all-new system, which is equally at home on a 1,500-horsepower dragster or a high-performance Pro Street machine. "It worked perfect right out of the box," said engine builder Pat McCreery, co-owner of family owned Nyes Automotive in Muncie, Ind. "We tried it on a 598 cubic-inch engine on the dyno and it worked perfectly, so we put it on our car and it did exactly what it was supposed to do right from the start." Armed with a tune created by the touchscreen’s calibration wizard, McCreery went straight to the track. "We bolted it on the car, ran the out-of-the-box tune, and the car went right down the track the first time – no stumble, no hesitation, no nothing," McCreery said. "We also tried it on another engine on the dyno. Same thing – worked perfectly, straight out of the box.” Racing on the day before her 19th birthday, Mayce amazingly reeled off six .00 reaction times in a row to reach the final round of eliminations. Her car was just as consistent, hovering in the 5.0s at about 137 mph round after round. "We still haven't really touched the tuneup," Pat said. "No need to. The Sniper Stealth 4500 has barely been on the market, and it's already out there winning rounds."
