Could we have just busted a widespread myth here that Dynojets read "higher" than Mustang upwards of 15-20%? Compare the two graphs below, the first on a Dynojet, the second on a Mustang, both on bone-stock LS3's. Compare the numbers:

% decrease, Dynojet to Mustang:
HP: (368-361)/368 * 100 = 1.9%
TQ: (362-342)/368 * 100 = 5.4%

% increase, Mustang to Dynojet:
HP: (368-361)/364 * 100 = 1.9%
TQ: (362-342)/364 * 100 = 5.5%

Let's calculate driveline/dyno losses:

Dynojet:
(425-368)/425 * 100 = 13.4%
Mustang:
(425-342)/425 * 100 = 15.1%

Right were we'd expect them to be for a manual tranny.

This is a far cry from the "15-20%" numbers that get thrown around. Maybe it's time to put this myth to rest once and for all...
