That's lower than I would've thought, considering that's not a Mustang dyno....

I'm kinda confused as well. Would like to see some more info. Speedtech made 620whp on 24psi through the stock air box, intercooler, and exhaust. So if Lucho is right then it does seem low to me.

Didn't they say something about pushing that turbo to the limit though?

According to the data on Speedtech's website, they made 620 whp on the 7670 kit through the stock airbox, intake, intercooler, and exhaust (using PI, though) at 24 psi.

I'm not certain I'd consider that pushing an EFR to the limit...?

The EFR7670 turbo is a 64lb/min turbo on its efficiency island which is about 650hp

So they are not pushing that turbo at that power level.

650hp at the crank, assuming no restriction in any other part of the setup. Granted, these dyno numbers are kind of useless without a log or baseline.

I get about 450whp with efr7670 on pump at around 16 psi.

I guess I'm stuck on Speedtech's data showing 620 whp at 24 psi.
