This Tahoe project was based in Savannah, Georgia, and our first task was getting a baseline horsepower figure. To handle this, we made the short drive out to Asian Automotive, where owner and lead mechanic Mickey Carter strapped the Tahoe to his Dyno Dynamics chassis dyno. Asian Automotive works on more then just import cars, and they can also do custom ECU tuning. After several pulls, the 5.3L laid down 268 rwhp and 281-lb-ft of torque. Those numbers are actually pretty decent for an all-stock Tahoe.
