With everything buttoned back up, Ernie took the pickup for another "drive," resulting in a leaner air/fuel ratio for most of the rpm range and slightly better peak torque and horsepower figures. This time we saw max torque of 215 lb-ft at 3,400 rpm and peak power of 156.9 hp at 4,269 rpm. The FAST meter indicated an identical 14:1 ratio below 2,800 rpm, a slightly richer 12.4:1 at 3,000 where previously it had been 13.1:1, 12.7:1 at 3,300 and never dropping below 12.4:1 again throughout the entire range up to 4,300 rpm.
