Modified did a "dyno dash" here in WA some years back, and while the Mustang did read lower, it was also preloaded @17% for some odd reason, instead of being an inertia based run like the rest.
FWIW, & cheers!

the difference at those numbers (20whp according to that article) will be amplified as you rise in power. We had a evo 9 that dyno'd 502 whp here that had made over 6xx at EFI's dyno in Connecticut. The difference showed in that article is still significant. Idk when a 20whp at 292-312 wasnt.
