It also depends on what standard is used for the dyno test. The standard that GM uses results in less horsepower than the normal aftermarket style test. Most dyno places use the baseline set at 60 degrees F intake air temp and 0 percent humidity, GM tests with a higher air intake temp and more humidity.
